That's different. Since you said you "put [your] 2009 MOW unit into II", it certainly sounded to us as though you had deposited it. With a Request First, you only give your week to II if an exchange is confirmed.
Yes, with a Request First, all you need to do is cancel your exchange request with II. Then call Owner Services and trade for points. You'll pay the two fees ($29 and $104) I mentioned above.
