Hmm, okay, thanks guys. And welcome portachking. :)
Keep in mind that it won't show duplicates in the list, unless you check the force duplicates box. So if you already have a game in your collection, it simply won't show up in the list. Could that be the issue? Otherwise, I'll have to dive in and keep asking questions until we can figure out the problem.
It will never be 100% perfect, so a game here or there that it doesn't find we may just have to deal with. But if it's not finding any games at all, obviously there's a problem I need to fix. Try checking that "force import duplicates" box and let me know if you get any listed that way.
Thanks guys. :)
