Can you open the license file in notepad and check the subscription date is correct. If it is, then FinalBuilder must still be using the old license key in either “C:\ProgramData\VSoft\FinalBuilder7” on vista, 2008 or windows 7 or under (from memory) “c:\Documents & Settings\All Users\VSoft\FinalBuilder 7” on XP/2003,
or under
C:\Users\Anne\AppData\Roaming\FinalBuilder7 or “c:\Documents & Settings[UserName]\VSoft\FinalBuilder 7”. Remove any license keys you find there and then install the new key again.
If the subscription date is wrong then contact support at finalbuilder dot com with the serial number so we regenerate the key (it is supposed to be regenerated when the renewal is processed, but perhaps that failed).
