Okay so I have broken a script while trying to change the mod dependencies because I opened it in in notepad and I did not unbinarize it first. The good thing is I made a backup of the file but the backup is a txt document. How do I fix this? I have downloaded arma tools and I have some of mikero's tools such as derap but I don't know what i'm doing from here. Any help would be greatly appreciated! When I try to load mission I am receiving a message that says mission.sqm, line 0: '.raP': " encountered instead of '='
