We guess that you received this error message:

This error occurred in builds of TO3000, earlier than TO3000 v10, build 1046. Thus, if you noticed that you have an earlier build (click the Help menu > About option), we suggest you update the program. You can do it by clicking Help > Check for Updates or downloading the software at http://to3000.com/download

If you have TO3000 v8 or 9 and you do not want upgrade the software, due to some specifics of Windows 7 and Windows Vista, to properly run TO3000, you need to run the program with advanced or administrator rights. For this, after you have installed the program, right-click on ‘Translation Office 3000, Version 9.0’ shortcut on your desktop and in the appeared menu click ‘Properties’. Then go to ‘Compatibility’ tab, select the ‘Run program as an administrator’ checkbox and click the ‘Ok’ button (see below). 

Note: TO3000 versions 8, 9 and 10 are no longer available. You can upgrade to TO3000 3D here: https://www.to3000.com/order/upgrades-from-previous-versions
