So, GTA3 MTA (which, for the record, pwns Vice City) works perfectly and I've had fun with it. However, due to lack of Aussie servers, I eventually tried VC MTA.
It is a completely fresh install of both VC and MTA 0.4 and I have uninstalled 0.3 MTA. Despite this, it gets within 1cm of the end of the loading bar (after clicking "Start Multi Theft Auto" on the main menu) and the entire computer dies. I get a unhandled exception error, and I can only get out of it by restarting my computer... all read-only attributes are cleared, it is unmodded (thus, no no-crc, no screwed up main.scm) etc and I can not find anything that would cause the problem.
Any help? I browsed through and couldn't find anyone else at all who had the same problem.
