The game used to work, but for some reason, every time I try to go into Sing Mode, it throws this error:(https://i.imgur.com/zUJKaVV.png)
I tried updating the game through the MLK gui, restarting my laptop, checking for compatibility issues with ultrastardx.exe (the one in the MyLittleKaraoke folder).
Every other tab/mode seems to work just fine except Sing Mode.

Did you maybe delete a picture file from the avatar images folder?
Try if deleting the config.ini in the games install folder solves your problem.
Well, flip. I accidentally moved one of the avatar files out. Deleting the config.ini worked; thanks :)
