1. I think there's not much you can do now, make backup of LFSLazy.stats file, just in case, and delete it. If that doesn't help try doing the same with other files (SplitPredict folder, LFSLazy.pbs, LFSLazy.wr, ...)
2. Second one is the same - go to data\misc and rename your now corrupted driver (Ayoub_Maroc.ply - there will be ^'s, they are color codes) and make new one with the same name in game.
