CF Client error?

Im getting a Error, its saying.
"Client File Corruption,game client closing"
I also tried everything. i mean everything!
i even looked all over google, to see other peoples ways, and that didnt even worked
I redownloaded it i restarted my computer i ran it in window safe mode, and deleted the game and re downloaded in safe mode. and still im getting this stupid error and the thing is, CF worked fine when i played it a couple hours ago, now im getting this message? i feel like im never gonna be able to play CF now because of this stupid error
