I ran into something similar, went to the support link at the bottom - and filled in the ticket and within 24 hours the problem was resolved.

preface for the people not reading ... some quick answers:
- our page on this Hard-SPL is always here:
http://rhodiumw.htc-unlocks.com/hard-spl.php
- license: you will just have to run the program on the PC with phone connected, normally you will not notice anything about the licensing, it is totally free for personal use!
- if you need help with license issues (when it says you already unlocked a device), you can send your message at:
