won $20 sat into $500 aruba sat tonight on UB, can i unregister?

[elliot]

unregister is listed as an option in the tournament lobby where i am already listed but i was under the impression that you COULDNT unregister from aruba sats, if i click it will the $500 get put into my account as tournament dollars? (i fully planned on playing it but now that i see that unregister is clickable i'd way prefer the T$)
