Re: Problem accessing King's Bounty?
Did you reinstall the player? I had to do that a few days ago and it worked afterwards.
Also are you getting it from the main site? http://www.metaboli.co.uk
Just thinking the affiliate sites might not have it fixed, and are linking to the dead KB (which will send you to an upgrade account page), you can tell by looking at the download link for KB, just hover the mouse over the download button, it should have yummy in the link not exent.
PS I never run games from desktop, I just have a shortcut linking to the My Games page and select my game through there, launching via desktop can sometimes fail to send the data to metaboli about what game to load.
