You can login then, I can't it says 'account doesn't exist' and I was in the middle of buying an MN when the site just went down on Thursday so put yourself in my shoes

Did you reset your password ? If your trying to login with your old password then of course it will say "account doesn't exist". Click the "I forgot my password" link.
Did the site go down without any notice ? I can't believe they didn't give any advance notice of it going down (I haven't got any in my email history from them).
Yes I tried that. I have another account I used that I could reset.
They only gave notice on Moolah twitter, I didn't see anything on Mintpal site or twitter and they didn't do a mailer.
They have made some basic mistakes BTW, e.g. they didn't test a full migration from the live v1 db for one, hence the big delay on migration and probably this issue with missing accounts is a data issue that came up when they tried the full migration for the first time
Anyway, just want to see my coins then i'm happy as i'm sure a lot of people are, no problem to use mintpal again if I see it working but not seeing that yet.
