CAL how to active an instance again - after the trial period?

Hi,

we cannot see our instance any longer and do not have an idea how to extend the
license for another 90 days.

We are using a developer CAL account for Netweaver 750 on HANA.

We are surprised that the CAL instance has gone - we expected to have the ability

to use slicenes for extending our trial period.

thanks in advance, best regards
Frank
