First thought is what did the error say and when. That is not much to go on.

dxdiag, crash report, something so we can pin where the problem occurs.

After I thought that I thought your video is not being recognized by the exe so maybe cleaning the system and updating drivers will set the links correct.

Well I know tinyurl is caused when you need to reload directx

What error message are you getting?

You can try to verify the game in properties/Local files

and/or post the debug.

The debug.err file can be found in \Documents\My Games\GC3 or \Documents\My Games\GC3Crusade.

You can upload it to a cloud service (DropBox, Google Drive, One Drive) and post a link here.

Also make sure that your are on the opt-in hot-patch, it fixed a crash.
