won seat into PS sunday million....but cant play

[vkotlyar]

so i used my FPP points to enter a satellite and won a seat into Sunday million. Unfortunately, i forgot that it was my wife's bday and we made plans to go out (Whoops). If i de-register, do i get the $530, a ticket to play a different week or do i get to suck on my thumbs while i get blinded off?
thanks
