That is good to know, thanks :) The only other Steam game I've played was Limbo and I wasn't modding it, so there is definitely a bit of a learning curve with this as I keep making assumptions based on past ES games that really don't apply here. And no worries on the "...have you tried turning it off and on again/is it plugged in?" question...it is the sensible place to start. And to answer it, yes. Each time I tried installing BOSS in a different location (taking my cues from the other thread I found that seemed to match my issue) I've clicked the icon at the top of the Organizer, highlighted BOSS, changed the path, pressed the modify key and then ok, and then launched BOSS from inside the program. Your first line of information, however, seems to have been the key. BOSS and Wrye are now seeing the mods I've ticked in the Organizer. :) I am now officially excited about this utility! A check on recent un/installation and whether the game menu has been started through Steam afterward so that the files can be configured seems like a worthy addition to the "is it plugged in?" repertoire...if memory serves the other thread I was reading on here involved someone having the exact same issue as me after a recent re-installation. Anyway, thanks again! I'd have stumbled through the solution later and likely never have known how or why it had been solved...and its better to know.
