For some reason when I try to add sprays to tf2 now, it tells me the file is corrupt. But when I add the same sprays to other games like counter strike source, it's perfectly fine. Anyone know the problem?
Here's one of the sprays where i have this problem.

Try adding the same spray as a *.bmp, *.tga or *.vtf file. I didn't think JPG was compatible.
