How to get your profile back:
1. Find the folders saved on your computer. The new + the old MNB folders.
2. Copy the OLD .sol file (from mudandblood2.swf) and paste it into the NEW folder (mudandblood2k.swf).
3. If it asks you, yes, replace the old file. That's the whole point.
It takes 2 seconds and it got my profile back. :)
