Hi Arthur, Thanks for your reply and help, most appreciated.
Yes I mean the seed, it is 81 letters long with a 9.
I was copying and pasting but decided to try and type it in after you asked.
This is what I get - it just whirrs (little cog going round and round) and doesn't log in.
I was assuming that if I had my seed then my coins were safe, so I'm not in major panic, but great to hear that from you and so pleased to have your help! :)

Update - it's finally let me in, but I have a zero balance, so I guess it's step 2 on that article now!

Next Update. I clicked the wrong button and got logged out and so managed to log in and my balance is showing now!! All very weird, but pleased it's all there!
So I assume I can carry on as normal with the same seed etc?

Thanks again for your support.
