Are you using an ISP that blocks adult content? I had a problem with 3 assuming that www.cutetube.com is a porn site. This is the address that YouTube redirects to after you authorise cuteTube to access your account. The only other possible problem is a database issue. You could try deleting the database by opening xterm and entering Code: rm - R /home/user/.config/cuteTube/Databases You will lose all your current settings if you do this. Database corruption seems to have happened to a few users, which is one of the reasons why I moved all the config stuff to QSettings for the Meego-Harmattan version.
rm - R /home/user/.config/cuteTube/Databases
