Hey,
Unfortunately, it looks like you're not the only one who's got problem with those two games...
The thing is I can't remember problems occuring with the 2.1 and that's what's disapointing me. I thougt it was related to the new version...
I don't know what to suggest... Have you tried with any other games ?
tTry with both version of TirAttack (check
