SONIC COLORS HELP PLEASE

Im running sonic colors USA version on R4 and the game wont save after each act so everytime i turn the game off i have to start at the very beginning of the whole game. Does anyone else have this problem, can it be fixed or can you point me to a link that works and saves correctly.

I have problems getting the game to run at all. Unfortunately the above link is quite old and not a lot of members seem to read it any more :(
