Question: Can you load the game and run a historic mission, not a career?

Have you got any backup copies of your saves?

If the game will run, but just not a career save, then it is the save files. If the game still crashes running an in-game historic mission, then the corrupt file is a game file. If using a mod manager, uninstall all mods and then test a game mission load. If it runs OK the corrupt file was a mod file.

If you re-install, first copy your MyDocuments folder where SH3 files are to the desktop. After re-install, and after testing a good load, put back the mods you were using and test load a mission again. Then copy the above files back to MyDocuments. See if you can load a save file.

Sorry, re-install has to include the same mod list as used, in order.
