Yes the space was in the wallet folder name /My Wallet/ I tried renaming it without a space & the same error continued.

I also made a test wallet in the Bitcoin Core software & overwrote the newly created .dat file, the next time I load the client it shuts down after telling me the data is not in recognised format.

I will need to look at what options I have & thanks for the message. I will take it into consideration.

I'm gutted this hasn't worked out.
