okay Grand I think I've got it here. I know you'll be busy but same at Alwil Software
this is from from Vlk as relates to Pro as far as I know - I wont bother to put in quotes --
in January, avast upgraded to version 5 which uses a new licensing model.
You will need a new license file to use with v5.
In order to get it, please follow these 3 easy steps:
1. open your existing license file in Notepad
2. go to
http://www.avast.com/resend-license.php, fill in the email address you used for purchase, the avast license key which you can find in the license file you opened in step 1, and the verification code
3. hit the "Resend license" button.
In a few moments, you should receive a new license file (called license.avastlic) which you can simply insert to avast v5 (e.g. by double-clicking the file, if avast 5 is already installed on that machine).
Thanks, and sorry for the inconvenience.

This doesnt work Grand - send an email to Vlk at vlk@avast.com and include a pointer to this thread.
Edit - if this what you mean by new (avast 5), then follow procedure with email, but yr Pro 4 should have worked okay from what I can tell.
