We thoroughly test all of our software. It doesn't mean a bug never slips through or that there isn't ever something specific to someone's system that would keep us from discovering the bug in the first place. We also offer a 15-day money back guarantee if you buy an extension or a suite outright so you do have time to try an extension and make sure it meets your needs since we don't offer trials at this time.
I'll leave this thread for Tech Support to address the issue you are experiencing.
