I didn't noticed date on threads I visited, sorry.
As to files, I checked them few times on different machines and they're corrupted on cd (when I enter them on cd or after copying them on hd I recive message about errors and can't manualy extract specific file) but cd has no visible damages and it's original not a copy.
Anyways I can live with that as long as other map sets will work.
Now I'm working on restoring my saves but they're crashing when I load them. Maybe playing with bad map files spoiled them so they're no longer usable. Hmm... I'll try to make new character of the same class (male wizard that is), save game as far as it will be posible and try switching particular files from old saves to new ones. Maybe this way I'll menage to get back quests I've done or items I collected (propably they'll be useless as soon as I move to another area but still ... ) and save some time.
