Can anyone help me fix these errors that will come up everytime I exit Xolox?

I'll get,
Xolox has caused an error in <unknown>.

Then I'll get an Application Error

Exception EOSError in module Xolox. EXE at ooooEC26.
A call to an OS function failed.

I downloaded Xolox. But I was getting all those errors. I uninstalled it again and re-installed it but I will get these messages everytime I close Xolox. Anyone know how to help me get rid of these errors?
