Hey guys about the crashing prob and lost of checkpoints I have a good solution here.

For crashing issue, 1st u need to turn off the full screen. Get into the game.... play for a while and when the error prob occur. Just Alt-Tab it and go back to game. DO NOT CLICK ON THE ERROR BOX. Then u can restore back to full screen and enjoy the game!

As for the lost of checkpoints (I must say this is f***ing frustrating), If it happens that u loss your checkpoints... There's 1 folder in GOW which contained all the checkpoints file... can't remember the name but the filename in it are like Chapter0.sav, Chapter1.sav etc. Now, if the last time u play were in 3rd act (for instance Chapter 30).

1. First, copy both Chaper0.sav and Chapter30.sav into a folder for backup.
2. Delete the original Chapter0.sav and rename the Chaper30.sav into Chapter0.sav.
3. Now get into the game again, dun choose continue campaign or start new game. Pick the 3rd choice (can't remember again ). Choose act 1, straight away it will lead u into Chaper 30. For sure u won't know which chaper u ended in so u might need to try a couple times to load the correct chaper.

Remember, no matter what u do, u will loss watever weapon u've pick up and started back with some default weapon. The tag will loss too, but who gives a damn about tat.....

Still, sometimes I still would lag out or my motinor screen will turn into safe mode for no reason. Well... playing a good game does require sacrifice.

Sorry, no idea about that.... I went to forum to check and lots of US players were really pissed by these issues. Many wanted refund cause a patch had yet to released. Tell me, have u ever played a game which does not allow manual save??? Or have u ever encounter games which your saved file can lost??? Why do they need this Window Live??? Just can't imagine this actually happened on a great game...
