I can join servers with all other maps with no problem. Somehow my dustbowl got corrupted by joining a public server. Anyone know how to fix this problem without reinstalling the game?
Windows Key + F > 'All files and folders' and either search your local hard drives or choose 'Browse...' from the 'Look in:' field and select just your steam directory to search.
I'm assuming you're running XP, if not your method of searching may differ.
I just got this error when I tried to connect to Dustbowl #1. I have a feeling it's not a corrupted map on my end, but the fact that I just installed the new TF2 update and the Dustbowl servers haven't updated yet. Can anyone confirm?
