Thin Client - Wyse 5070 - Login is Denied (ThinOS Activation license is note avaliabe)

Hey everyone!

Today i'm facing a problem on a Wyse 5070.

Dell customer support fixes Wyse and sends me version 9.1.

In order to be able to update to the latest version, I need to update to 9.1.3129 and then update to the latest ThinOS version 2303 (9.4.1141) , 2303 (9.4.1141). (This process I managed to do through WMS correctly)

But after that... I got the message: Login denied (ThinOS activation license is not available)

Any suggestions I can make to resolve the issue?
