Thanks Scottiesmum, you seem to be having the same problem as me, I must have installed it now five times and uninstalled it as many.
The old version worked a treat, don't know where it went though!
I wonder if it is the 'new holiday version' that is the problem? I tried the step by step guide but that also stopped after a few seconds!
I shall be away from home for a few days, I'll try again then, maybe Avery will have an answer to my query by then.
