I d.id change my password and had an Apple ID once again - Istarted mac up and pressed command and R. Great, I then had options come on screen. So I opted to reinstall Lion OS. Apple decided in its wisdom to think my password was wrong -it wasn't, but hey ** slowly getting there., all set Swapped password again,pressed install and a message came up saying that item was not available, please try again later. So I went to bed and I'll try again tomorrow. I'm pleased that there's light at the end of the tunnel - fingers crossed. Again, thanks, I would never have got this far without you guys. I'll post again later - I know you are all waiting,with bated breath,. to see if I get the mac working again 'night all.
