Lightroom stuck in trail version

Hello all,

Right now my lightroom is stuck in the trail version. Each time I startup LR it opens with "trail expired'.

When I then say "buy lightroom" it sends me to a window telling me purchase is done. But then I still can't enter lightroom because it keeps saying I am in trailmode which expired.

Any tips or solutions?
