Plutonium

I launched plutonium a while ago, it updated. because i never opened it for 1/2 months, opened it but iw5 suddenly had this error. I went into %localappdata%\Plutonium\storage\iw5\maps\mp\killstreaks , all i found was _helicopter.gsc and _nuke.gsc. _killstreaks.gsc was not there. but i'm still getting this error
