Every time i open program it asks key again?

It’s really weird but today everytime i open “YourUninstaller2010” it says that it is the trial version and i have to enter key or continue with the trial????!!!!
I enter key and it accepts but then again the same game!!!!
How is this possible?
Answer #1
Maybe it’s missing some patch. Don’t you have one?
Answer #2
try revo uninstaller, its way better!
Answer #3
Maybe the app got updated to a newer version and the key is no longer valid, only momentarily? Or the key got blacklisted? Try finding a different one.
