Anyone else have probs with hot pursuit 2 demo??

Hey I just got the demo, and am having problems with it, textures get mixed up and wierd like 5 mins into the game, and when the textures are fine, it freezes! I dunno what wrong! it does the same even when my video card is at stock!! I have no problems playing any other game.

copy the files and folders from the cd to your game directory, game spends a lot of time reading the files from cd and often freezes the game
