Problems after Plesk Update to v8

[giga]

Hello!

Yesterday evening i updated my Plesk from v7.5 to v8.0!
But my licence-key is only valid for v7.5.
Is is possible to become v7.5 back without a
complete re-installation? Unfurtunately i've no backup!

Greetings

Thnx for reply. But when i update my key and i want to make a new installation in future, i only can install 7.5 and then my key is not valid for 7.5. My server is rented so i can only install 7.5. Is ist possible to install the 8.0 update without a key for 7.5???
