Shut Down, unplug from wall, press Power button a few times and hold it down for a few seconds.

Turn back on.

I tried that without sucess. I solved it by remove and reinstall. It took me 4 times, luckily I saw à post that you might have to repeat it. Finally resolved... Also, my setting-files were in different places than in guides. So be sure to search for them and delete, others with problems. Thanks for reply.
