I'm computer retarded. I have a feeling it might be something simple, anyhowww...

so basically I started streaming the other day. My game was fine. I didn't change my cfg at all. I didn't even shut my computer down. I come home from work today, start tf2 and ingame my cfg is completely erased. Everything is set to default, crosshair, fov 75, game sound, mouse sens, ect. My ingame binds still work tho. Whats weird is that in the cfg all my original settings are still there. I tried reinstalling tf2, getting the cfg off my old computer and replacing it over the current one on this computer. None of it seems to be working and its still set to default. I wouldn't have a problem just redoing the whole cfg from scratch, but when i move my mouse is also feels slightly delayed when i try to rocket jump. not really sure wtf happened since i didnt touch anything.

Windows allows me to delete the cfg, but it won't allow me to delete the tf folder. It asks me for administrator permission. Steam cloud isn't enabled. Any ideas?
