I assume you mean this program (I didn't check our download site): www.brothersoft.com/messenger-detect-80757.html

The page I link to contains the url of the makers site. I think it's best to visit them or contact them with your questions. I don't expect many of our members visiting this forum use this software and can answer your questions. Moreover, spying programs aren't very popular here.

Paying the $26.95 it costs anyway gives you the right for support. Use that.
