Maybe change it to something else than default, than back to default again to update the registry correctly... If you don't have any other, maybe just clicking on Default again even if it appears checked will fix it. But don't worry that's not part of your main problem. But are you using Run As... to start it? If so, you shouldn't... If it doesn't load at all otherwise, then see the topic 'Continuum won't load' in the FAQs... That would be caused by some antivirus or anti spyware software. Maybe some files are read-only for some reason... Right-click on your Continuum folder, properties. Where you see the 'read-only' checkbox, make sure it is unchecked. If it's grayed, click once to check it, and again to uncheck it completly. Also, go in your 'Zones' subfolder. If there's anything there, delete everything you see... Maybe it can't overwrite files for some reason (note you can just move the files to a new folder if you don't want to delete every arena you've gone to) And now I'm out of ideas
