IV MP fucked my game?

[Vegas]

I had some saves for my favourite missions, and after I installed IV MP it's like the game settings are default and all saves gone, and windows live is bothering me for registering... watch out for it... gotta buy the game

Why didn't you bought the best game made by rockstar?
Oh and.I don't think you are allowed to discuss about warez so better edit ya post
