In the hotfix of 11-05-2012 only the exe has been changed, so the checksum was not changed. If you use the version prior 11.05 then you have an old exe. Replace only the exe or the re-apply the entire patch from the Beta 3 thread and report if CTD still happens.
Crashes here as well playing JAP - last I saw in the message log was a diplomatic deal between GER and JAP. It did not crash when loading up as GER.
Savegame did not crash with 1.07 (after removing two 1.08-only command lines) playing JAP.
