This was really odd... I logged in earlier tonight and selecting "Play" gave me the "you have no content IDs" etc, message, which confused me, but I figured maybe my card expired or something. Checked info/card, everything's fine, I check canceled/active IDs, my IDs are active. So, try again, and the same thing, "You have no Content IDs, please activate, blah blah blah" and so forth. So, I figured maybe it's a glitch, reset my PS2 and I was able to log in.
Oddly enough, I mentioned it in my linkshell and a few others had the same issue. Anyone else have this problem or know what the hell's going on, if it's related to the whole FL+ thing?
