I recenly bought the first 3 POP games for PC. The first one freezes at the first checkpoint and the third doesn't allow me to save the game at the checkpoints... I can continue playing but when I quit I have to start ALL the way at the beginning again. Am I supposed to press a particular key at the checkpoints or something? Oh, and I downloaded the first game's patch but I couldn't copy it onto the original .exe. I am not a pc genius so PLEASE HELP!! (The games themselves are great)
