Hi, thank you both for your replies - I really appreciate it.

Yes, I checked both those bitcoin explorers and there is a confirmed balance on the address. This exactly matches the balance shown on blockchain.com under my 'imported Bitcoin addresses', which is the same address shown in my private key window.

I'll buy a new usb stick tomorrow and try the desktop version of exodus as suggested. The simple steps and guide are really helpful.

I will let you know how I go.
