I have no idea if it was the latest WB5 or Iconpackager. I just now updated them after SDC updated to its lastest version, and after rebooting my PC completely froze. I had to go into safe mode and restore them to the previous versions and everything is back to normal now. So it was one or the other or both. Sorry I can't give you any more info than that, because I couldn't do a thing with my pc other than restore the previous versions of WB5 & Iconpackager.
