Not possible to use Lightroom suddenly

After upgrade of mac it was not possible to open Lightroom anymore. When application is opened, it just shows "try this product fot x dollars per month". I haven't tried to subscribe to additional accound, I have an account already. Will the additional account have the data from the original one? Would i have to pay double (original plus double). Is there a way to contact Adobe, and do they have some type of cosomer support for these questions?
