license activation failed with 6.0

Hi,

after upgrading from 5 to 6.0, a message appears saying my license key is not valid. We bought it 8 or 9 month ago, so it shoukd be within maintainance. What to do?
(I tried with direct references and NuGet packages).
The installer of 6 seemed to accept the license key, but after using the licenseActivator tool, it says the license is already activated for 5.0

Thanks
Hi Andi,
I have sent license information to you via email.

Andrew
