First, make sure your USB hardware key is really broken or it is just a case of a problem with USB drivers. It is less likely to damage the USB key: due to mechanical action, action of electrostatic discharge, etc... If a small green light on the USB key is lit while the latter is connected to the computer - everything should be fine.

Firstly, try to uninstall TeleCAD-GIS application and then re-install. Also check if in meanwhile  another application that uses the USB drivers was installed. So far, it was shown that only some USB drivers for large format scanners can affect the operation of the USB hardware key. Uninstall the drivers and reinstall TeleCAD-GIS application. If this does not help - please contact technical support.

Open TeleCAD-GIS, right click in the model and select "Options ", then move to the "PROFILES" where you will see at least two profiles "<<Unnamed Profile>>"and "TeleCAD-GIS 2006. Double-click on the "<<Unnamed Profile>>", then select "TeleCAD-GIS 2006"and click on "DELETE" on the right. When you have erased profileTeleCAD-GIS 2006 "then press OK, then close and restart the application"TeleCAD-GIS.

During the automated creation of graphical reports, or input in headers,  we can not see letters (ščćžđ), but instead  strange characters appear.

The problem is in the Regional Options settings that are changed from the Control Panel. If you use a localized keyboard (Serbian, Bosnian, Serbian, Slovenian) in the PDF document, whose link is given below, describes the alternative solutions on the Windows XP (SP2):

Pokrenite Start /Control Panel /Regional and Language Options. U dijalogu koji se potom otvori (tab: Regional Options) u grupi Standards and Formats izaberite jezik koji koristite. U polju Location izaberite zemlju koja odgovara postavljenom jeziku. Pređite na tab Advanced i u polju Language for Non-Unicode Programs izaberite identično podešavanje jezika kao i u Standards and Formats tab-u. Kliknite na dugme OK i restartujte računar.

Run the Start/Control Panel/Regional and Language Options. In the dialog box that then opens (tab: Regional Options) in the Standards and Formats group, select the language you use. In the Location box, select the country that matches your language. Go to the Advanced tab in the Language for Non-Unicode Programs field, select identical language setting as in Standards and Formats tab. Click OK and restart your computer.

In addition to the classic update by downloading the installation from the download section, it is possible to autoupdate by downloading and installing the TCG update file.

Find more information about how to download and install  TCG update itself on the download page.

One of the reasons for this might be going to a mode for printing.

Call the command "Preparation of situation for press??"  from the Sketches menu. Click on the letters "Work??", so the infrastructure goes into work mode, and then click "Configure".

More on the operation and use of this command, see the Documentation guide.

Propreties initialization is done when you start an application, and is, therefore, necessary to restart the application in the following cases. 

After adding the cable in cable catalog, the shaft in shaft catalog and change of cable and pipe type in the system settings.

Commands COPY, PASTE, MOVE, EXPORT,... are not executed, and in the command line you do not get any message or in some cases, the message "Wblock operation rejected due to a proxy object that does not allow copying." is shown.

It means that in the drawing you have objects that are created with other Autodesk application, and it is usually Autodesk Land Desktop or Autodesk Architectural Desktop.

One solution is to download "Object Enabler" with Autodesk site (section Utilities & Drivers) for the application you use. AutoCAD 2006, AutoCAD MAP 2006 3D

The second solution is to save drawing in DXF format v.12, and then open it and save as DWG format of desired version.
