From Hero to Zero

I'm getting cross with my Guitar Hero game now. Although playing the game is great fun it does seem to have the knack of losing all my saved data. For the second time it has forgotten everything and lost all my hard earned progress. I'm pretty sure the game is at fault, in that the save file is there on the memory card (and I can copy it around and stuff) but the game just refuses to recognise it. Most annoying.

I think I'm going to put my PS2 version up for sale and then get the XBOX 360 version when it comes out.
