Same shit happened to me, only it happened to me when I put in cheats and tried saving. Later the game was unable to load, so I had to start from stratch. Now I'm a little ways into the game but I've lost interest. Truthfully, I think the game's OK, but there's nothing too impressive about it (in my opinion). I would still have to say, best GTA game would have to be Vice City, III comes in a close second though.
