License key invalid after 9.2.3 to 9.5.4 update

[Surfgatinho]

I just ran an update from 9.2.3 to 9.5.4 which worked fine. Now I have been locked out of Plesk with the message:
"The license key is invalid. In order to use the Parallels Plesk Panel, please obtain and install a new functioning license key."

This goes on to tell me I only have a license for 1 domain etc.

I didn't think that a new license was required to update from version 9.x to 9.x?!

Thanks in advance,
Chris

Yes, you should update your license. Contact your sales representative.

Would this effect emails? Email service seems very unreliable now?
