Hope someone has a solution to my problem.

I upgraded to Windows 10 a couple of months ago. Tonight my laptop was auto-updated with Windows 10 updates. Doing so corrupted some files in my current installation of DP7. So I repaired my installation and was then prompted to register my copy of DP7. The problem is now I'm being informed that I have reached the maximum number of registrations for this version, and can't use the program. I have a project due in the morning! Already contacted Xara support and received the auto reply message (no help though). Any suggestions? I'm in deep need, but don't care to spend the money to upgrade to the latest version, shouldn't have to.

Thanks,
Steve
