Hi Larsik,
I am sorry to hear the trouble on your side. Please let me assure you that official license files never expire. If you do have "expiration" message, chances are the official file has been overwritten by temp ones. First of all, let's get your license file re-generated. In order to do that, I will need your buyer's email@ or the domain name registered. I searched by LARSIK with no luck. So please help me find your order.
Looking forward to your speedy reply
