Crap like this is why people hate computers. How's some non-geek supposed to figure that out?
When I tried to transfer the domain, support was baffled about why their standard transfer processes was was failing just for my account. I think it went on for a few weeks but I wasn't in any hurry so I didn't bother them much. They kept asking me to try again a bunch, but nothing they changed ever worked. At some point the idea just hit me that the password was the same from that MySQL issue. By that time I had moved on to using a new password everywhere because of that issue, but had never switch it for this account. So I switched the password, tried the transfer again, and it finally worked! I told support what I changed and why I think it might have been causing an issue but they never did directly confirm that was the problem. I'm still pretty sure it was. After I changed the password, they sent me an email with the new password in it, naked as the day it was born.
Everything was smooth.
Did you try that instead of e-mailing?
(For the record, for me, it'll be like 10th time I've bought it, so it's working for MSFT. [The first time I bought it was 5$ to Notch's PP account.])
It's a burden, but you're in it this far, to the point of telling us strangers about it ^.^
I was migrating 5 accounts at the time, and it hit on the second or third so I was baffled for a bit.
