Hi, Why is this so complicated? I have enjoyed using PTE for many years, now on version 7.5.10. I want to upgrade to version 8. The current licence key is nearly the length of a book! After much cursing, I managed to extract it from my registry and found it in an old email from you. But when I try to enter it in the appropriate upgrade screen, I get the licence key is incorrect or damaged. I've spent an hour on this and have lost the will to live or use PTE. Regards,
