error message trivia pursuit

[vickstorm]

I have the trivia pursuit but I keep getting a error message kxmxzmfcyg.exe message and it won't let me use it.  Don't know what this is. I was using the triviaknowitall right along and now it won't let me use it.  I even deleted it and tried to download it again and that didn't help either so not sure what to do.
