Plutonium

Well I went into my gamefiles and removed the zone folders as a whole and redownloaded those however now when I go to launch T6 I receive this issue "Missing config file "default_mp.cfg" during initiliazation. May need to add to code_pre_gfx." Any help would be wonderful thanks!

"Fastfile for zone 'code_pre_gfx_mp' is corrupt or unreadable" I have the base game from steam, I've had it for years and I have it completely updated and even verified my files but am still getting this issue when trying to launch my game, I tried using piry but understand it is down for the time being, what should I do to fix this error?
