Hello Noel
If it is failing on opening the PCSoft repository and if you can get to it before it tries, make sure that the Windev General options Help is set to use Local Help. That may stop it going out to the web to open the repository.
In the old days, holding the shift key down when Windev opened used to stop it loading previous projects so that might help here ??
Another thought is to uninstall and on the re-install choose the option to use V24 settings.
To live dangerously, you can also clear the Windows Registry for PCSoft HKEY_Current_User\Software\PCSoft. That will guarantee a clean start
