Preview and publish shows error after a while

OK, so  I wrote the above message, uninstalled SL, reinstalled and now just got an error...

Not sure what can cause these errors. I'll open a support case soon hopefully this can be fixed. But maybe other users can see this and write if they get strange errors recently.... For me it happens more when trying to preview but also when clicking on the player.
