My copy of Ultimate Party Spin's part number is ASGUPSMW1001-00.... Your copy has "NV" in there. I am not sure if that means Nevada but I have a copy of Reel Winners Multispin with "NV' in the part number that can't find my wheel. This version also doesn't have the BET 90 TO ACTIVATE THE WHEEL...whatever that says.
When the game loads up can you Calibrate the wheel or test it? I know when loading a 3 reel game on a 5 reel, and then going back to a 5 reel game, you have to calibrate the reels to make all 5 work again. Just a thought.
