Its odd, I have been modding another copy of GTAVC for a few days without playing my MTA copy. The things I did to my other copy was mainly main.scm coding for making mods.
When I go back to play, I get a c00005 error. I uninstall gtavc and mtavc, doesn't work. I uninstall ALL copies of gtavc and uninstall mtavc again. Now I reinstall again and still no luck. I see theres a file in c:/windows called "mta" which I notice isn't deleted during uninstall.
After deleting that and reinstalling (I noticed the install placed a new one), my game worked. The only problem is
1. It did not know where the mta.dll.dll was EVERYTIME I re-started MTAVC. To fix this I added:
[game-exe]
location=C:\Program Files\Rockstar Games\Grand Theft Auto Vice City\gta-vc.exe
to the "mta" file in C:/windows. Thats solved that problem. However, I still have problem 2.
I get this error:
I tried different exes, originals, replacing them, blah blah. Nothing. I don't know why these problems started in the first place, but it seems my only option is to work around them since uninstalling and reinstalling isn't working it's magic anymore.
