It seems to have been stable for some time now and other transfers have worked. Just double check that you are putting in the active key for the transfer.

I'm pretty sure it's the private active key. But I can't double check because I can't get in and I can't find my master password either. I've never had a problem before.

I need to do some stuff and before getting ready for bed so I'll have to leave it for now and try again tomorrow!

The system was giving me the 504 gateway timeout message earlier today. I think one of the servers was/is having issues. It should be fixed tomorrow.
