Like what is going on with this game... Played 2 hours yesterday, jumping back in this morning then boom no more save games? I have to start from scratch?

Playing online is another horrible experience... I have to retype my damn serial each time...

Frustrated like hell....

your Save Games folder for Crysis 2 is probably set to read-only. It's located in: C:\user\Saved Games\Crysis2
Check if it's read-only, and if it is, uncheck that option in properties.
