My scores vanished

[Katra]

Today when i opened CW all the scores had disappeared.  ??? I can't even get into Chronom since the game thinks I haven't played story mode. (the custom map files are still present.)

At first I wondered if running AVG PC tuneup might have caused this; but I played both custom and Chronom maps with no problem after doing so.  What happened; and is there any way to find the missing scores?

It seems something happened to your GameData.dat file. You can read here where to find it: http://knucklecracker.com/forums/index.php?topic=368.0

If you moved it to another location you can just put it back there. :)

It may have recognized your GameData.dat file to be a temp. file, so it deleted it by accident. You may be able to perform a recovery, but I am not sure.

I'm not sure if AVG puts 'suspicious' files in quarantine, but if so you will be able to get it out of there.

A copy from a backup will also work.

Windows system restore won't help you out here, as it doesn't affect data files, so don't even bother doing that.
