Great news! I found my original default wallet on a separate hardrive....the reason the wallet in my above description wasn't showing all my bitcoin was that it wasn't the wallet that was linked to the watching wallet!.....
I can now see all my bitcoin transactions that mirror my watching wallet and the default wallet is live. I now have a new problem, when I go to the wallet menu option and select seed or private keys it asks for my password which I dont have (and genuinely dont remember setting). Is there anyway I can setup a transfer my coins out without the password now I have the default wallet live?
As per HI-TEC99 comment, I have now located a line of code in the plain text of the wallet file called "seed" starting with kKeQ - this isn't a seed phrase but I was wondering if I could use this somehow to regenerate the password or send the coins?
Thanks in advance
