Lots of wacky things happen over the weekends still with schedule changes being rolled through the system. If the PN inventory is still available then the OP can upgrade again. If it isn't then I'd wait until Monday before getting in a tizzy over it and calling to have it fixed.
OP's flight is tomorrow. S/he needs to call now. In looking at the upgrade list, it's a 24 seat F cabin, no way of an equipment downgrade (unless it was originally a wide body).
ETA: Not sure why this was moved to the "how it works" thread. This issue is about being downgraded.
