I'm going to format my PC this weekend because it sucks and I can't stand it anymore.  Anyway, are there any files in the World of Goo folder I can backup and over-write after I install it again and it'll have my saved game?

Thanks.

Look here to find out where your WoG profile is stored. Place it back after your re-install and everything will be saved.

Awesome, thanks!

I did what you said, I copyed the "pers2.dat" file, I formatted and reinstalled Goo, replaced the file and it's not reading it.  It just has 3 "new" profiles and I have to create my username.  Is there anyway to force to to see my old "pers2.dat" file, or am i screwed?

This is just a guess, but may be worth a try:

1 - make sure you have your original pers2.dat file somewhere safe.
2 - start WoG and create a profile with the same name as you had before.
3 - overwrite the new pers2.dat with your original.
4 - hope it worked...

If your on Vista make sure that you have followed the instructions elsewhere on this forum for setting compatability and administrator privaliges. That can cause a problem where your progress isn't saved.

I am on Windows XP, but what you said above worked.  Creating the profile, then overwriting worked, thanks again!
