upgrade from 4.0 to 4.5.1 problem

Have the same problem!

[QUOTE=midori;4440]

I asked for an upgrade to 4.5.1, but have not been able to license a single copy using our existing license number. Now an attempt to re-license existing copies of version 4.0 that have been unlicensed, results in a message saying all licenses are used up.

Do all 4.0 licenses have to be uninstalled before 4.5 can be used?

What am I doing wrong in trying to activate our 4.5.1 versions.

Thanks,[/QUOTE]

I do need more information from you regarding your license number and the person it is registered to. I will contact you via private message for this.
