Yay! After nearly 3 days I'm now back online and upstreaming. Seems the problem was with a file in my www folder that wasn't being handled properly by Radio. I've not spent enough time looking to see how upstreaming works so maybe now I will. Anyway, thanks to André in particular who helped me get back online.
Released v0.92 of the assetmanager tool. This version copes with the Windows 2000 'thumbs.db' file that's created when you view a folder by thumbnail icon.
