After completing the main quest of Oblivion, I downloaded all the extended mods from marketplace (Shivering Isles, Knights of the Nine, etc). All of a sudden, I can't cast spells. There is no curse, intelligence is normal, no active effects, and I've prayed at Chapel - still can't cast even the most basic of spells. This is killing me! I saw a similar issue posted on a forum for the PC and the fix was to "open up the console, click yourself, and type "setav silence 0". I'm a basic XBOX 360 user and this doesn't really help me. After spending a lot of money on these downloads, there is no way I can continue with this game unless I have the ability to use my magic. Anyone have any ideas? I was thinking of how I could "silence" myself to see if that retriggers the clearing of the silence, but can't find a simple way to do it. Also tried turning the controler on/off and that didn't work. HELP!
