Having the worse luck with this. Nothing will link for me. DMA keeps telling me my account cannot be linked. The other retailers just errored out when I tried to link them and now when I click on the other retailers nothing shows up at all, just blank. It's completely broken on my end.
Guess I'll be waiting.
EDIT: OK had to do some work arounds to get anything working, in case others have the same problems. Not sure if it's a problem with firefox or what.
In order to connect retailers I had to clear all cookies, then log out, then log back in. Once one retailer connects, repeat the process all over again for the other retailers. I got VUDU and itunes to work this way. No luck on google yet.
As for migrating my DMA movies. I kept getting a message that the account could not be linked. So I cleared my cookies. Logged out. Then I went to the DMA website and logged in there. I then went back to movies anywhere and logged in there. Clicked to migrate my account and, boom it went through first try.
So yeah,quite a pain on my end but seems like I managed.
