TorrentIt Online Gaming

So I got a message twice when I went on to the mixed server saying that I binded a key to run 'vstr' Scripts... What is it and how do I get rid of it? Any help would be appreciated. :)
Oh and it didn't kick me on the TDM server after I played on it for a few mins only seems to be on the mixed.

Its prob a bind not allowed on the server..goto call of duty 4\players\profiles\(your profile) There will be a notepad file called config open it and search for vstr and delete.

The problem is caused by your F3 key
Delete the bind you have on that key and it should be fine mate

Thanks for the responses...I went into my config file and deleted everything that I saw that had vstr but i must of missed something cause that didn't work it was a big chunk of text
I don't have anything binded to f3...So a guy I know told me that I should try going to the default controls and that worked for now I guess lol...Thanks for the help guys I appreciate it
