Hi,
Thank you for your reply.
After updating yesterday, a message appeared "Authorise This Computer" so I entered my registered email and password.
I ripped a couple of discs and after I was done, I switched off my computer. But when I came back a few hours later and started DVDFab again, I got the same message "Authorise This Computer" So I did it several times and the problem still persisted.
So I signed into my DVDFab account and de-authorised my computer. I launched DVDFab again, entered my log in details and it appeared to have worked. But several hours later, the same problem "Authorise This Computer". So I deleted DVDFab, reinstalled it and the same "Authorise This Computer".
I've tried installing an older version (10.0.7.1) but to no avail. Only this occasion The error message now says "You Cannot Authorise This Computer" "You have already authorised 1/1 computer(s) with your account. To authorise this computer, you must first de-authorise another computer, reset all computer licences or purchase a multi-computer licence from DVDFab". But I can't as you only have one opportunity per year.
I only use one computer and the problem only started after the new update. Anyway, I have emailed support, so I'm awaiting a reply.
Thanks,
Dave.
