So, I've played this game several times before. Tongiht, when I went to play, I chose a song and got the message that player 1 is not assigned to a mic. So I went to tools, options, and record to fix this....but there's nothing in record. Literally the only option I get when I go there is "Back".
If you're using the Mac version, maybe thiss (http://www.mylittlekaraoke.com/forum/index.php/topic,457.msg2781.html#msg2781) will help you. I've also read that running it with sudo fixes the issue as well. Seems like it's caused by an OSX update.
If this doesn't help, you might want to post this on the Ultrastar Deluxe board (http://ultrastardeluxe.xtremeweb-hosting.net/index.php). Unfortunately, we have nothing to do with the core programming of USDX.
That worked! Thanks
