@fabian.zschocke,
We now have you registered for commercial support under your company's license/entitlement. Support registration is associated to the license/entitlement that you are using. I believe, your previous support registration was done while you were accessing/obtaining the licenses from your university's license server.
For the run time or licensing error - that is an issue with the previous version of Lumerical that is not related to the support registration.
