"Free trial perios of ReSharper 9.2 is over", after 4 days

My company has been a ReSharper subscriber for many years, but we have not yet migrated to VS 2015 and RS 9 (we'll be there soon).

But I installed VS 2015 and RS 9.2 4 days ago on the 17th of September to evaluate some new features. I started my RS 9.2 evaluation that day. Today I have the message that my "Free trial of ReSharper 9.2 is over.". Do I have no choice now but to roll back to RS 8, after a 4 day evaluation period (2 of which were weekend)?
