Oh cheers I didn't see that sorry, I think when I set the <EnableAutomatedImports>true</EnableAutomatedImports> to false then true again this is when it's happening but I'll wait for the update, thank you.
I can't believe how bad this has screwed Launchbox up, now I have no artwork for anything and the game titles are all just the short filenames, unbelievable. I may aswell just delete if it isn't going to be fixed any time soon.
