Thanks Paladin181 for the information, I didn't know that.
Now I'm going to try what you suggested DaGrooved1
There's a 90% chance that's causing your sky problems, if you can't copy them it's probably because of a scratch in the disk, or they're corrupt. If you have a cd burner try putting the cd in that and copying them, as usually cd/dvd burners are better at recognizing files on scratched disks, if that doesn't work I can try to make a zip file of my sky dat files for you.
Dang, my cd burner isn't connected, so can I get that zip file? Thank you.
