Why doesn't my Chanalyzer Pro key work?
You may be trying to activate a Chanalyzer Pro key in Chanalyzer 5, which is a newer, upgraded version.
Chanalyzer Pro keys always start with XUU1. If your key starts with XUU1, ensure that you are attempting to activate it in Chanalyzer Pro, not Chanalyzer 5.
If you just ran an upgrade from Chanalyzer Pro, the older version should still be installed on your machine.
We strongly recommend upgrading to Chanalyzer 5. Find out about the discounted upgrade path, or download Chanalyzer Pro here.
