Where to find support for problem with multi license education

Hello,

During my experiments with learning and setting up 5 computers in our school I messed up the licenses. I tried deactivate a license in order to give it to another mail account but that does not seem to work. Now I can’t use that license. Who to contact for fast help?
I’m the teacher trying to setup this but it I have to do it in my spare time so please not a time consuming route. Thank you.

Kind regards,

Please send me an email at d dot spreadbury at steinberg dot de with details of the problem, and I’ll do what I can to resolve it as quickly as possible.

Thanks in advance.
