I've had similar problems, They went away when I took off the neck made sure those electric sensors were clean and made sure my cord was plugged in the wiimote right...
i had a problem like that with my guitar too... when i first unboxed it and turned on the game, my strum up didn't function... but after a few minutes it was workin fine... pretty strange.
maybe the connection to the wiimote just needed a little current run through it or something, haha
Yeah usually when any part of the guitar doesn't work you gotta do at least one of 3 things.
1. Dis/Reconnect your Wiimote.
2. Disconnect neck of guitar and blow off the little sensors making sure they are clean.
3. Make sure the neck is pushed all the way into the guitar.
If none of these work, and you still have the receipt and you bought the game less than 60 days ago, Red Octane will give you another guitar for free.
