AR causing errors...

[Curlystraw]

I have a computer that...It has no graphics card. I managed to struggle through classic to the master hand, and the stage final destination worked much faster. I tried using the AR cheat for all characters and levels, but every time I try to start a melee with the cheat active, I get multiple warnings:

goes on like this until I click no...

I'm running Vista x64

I'm having similar problems; it's only with AR codes that I add. The default ones don't give any errors (although most of them don't work).
