I have same problem since upgrading to the new version (although because of my problem I can't even tell you what version I now have) 2.11 something. I upgrade and TV guide, favorties didn't display. I looked at i and no channels were showing. I logged on to my account ICETV and noticed I didn't have the appropriate API Token. So using the widget I tried the deauthorise option - nothing happenened. I unloaded the widget , closed yahoo engin, ran the reset reg routine per the support guide and restarted yahoo I reloaded the new widget. Got the prompt to authorise. However the authorise option doesn't work. So I retried the whole process again but this time also uninstalled yahoo widget engine and rebooted to start from scratch. Now I am stuck with an authroise screen which won't go away.
