So I made a map a couple of years ago that I unfortunately don't have as a map-file anymore. Only as a mod folder.

Now I've decided to start a new map and was wondering if it's possible to somehow open this old map in radiant. I would like to copy a part from the old map into the new one.

I'm getting this error:

Server script compile error
Could not find script
'maps/_zombiemode_perks_black_ops'
maps\_zombiemode_perks_black_ops::init();

I downloaded modtools that automatically helped you with black ops perks.

I've been searching for topics with the same problem but don't seem to find any. Somebody help a beginner?
