Thanks for the replies. I have tried the ismine command on the console but it just keeps saying "false", and ticking the BIP39 box, made no difference.

I go file/ new/restore, i name wallet, then choose standard, click already have seed, enter seed, leave bip account as 0, enter new password, then end up with another empty wallet. Why do I keep having to entering a new password? It doesn't even give me the opportunity to use the password that I already have..

I know it's all spelt right as I copied, pasted, and printed it out.
