File CRC is WRONG [CRC is wrong! (1229210729 -154625555)]

I have no idea what could cause this for one of my players. All of my other players can include my gamemode’s cl_init, except when he sends me his console log he gets [CRC is wrong! (1229210729 -154625555)]. I’ve told him to restart steam, restart gmod, etc… Any ideas? The only thing that I can think of that is different is that his system language is in Portuguese.

Re-validate files and delete cache should hopefully clear it up.
