This solution just worked for me. I was updating my mods, including skyui, and i experienced ctd on using inventory. I deleted all skyui files, but it didn't work. I then deleted inventorymenu.swf and that fixed it. Where are you finding this file? I looked in the Interface folder and it isn't there the file is found in skyrim/data/interface ... but I rename the file and it didn't help and the game also didn't replace it with a new one. Might be that there is a seond file at a different location ? Btw, I can "play" the game just fine (some mods won't work of course without skyui) as long as skyUI is not installed. So I guess the bug is in corrupted files. Reinstalling skyui didn'T help though...
