ok so I have a 2 prong answer for you!
1) I followed the directions, I deleted everything, went offline turned off AVG etc, and still it failed so I took the screenshots as the FAQ suggested
It still failed, so having read through the FAQ one of the things I noticed was it suggested trying the windows and not the Windows 64 bit version, and what do you know!! It is working!!
Interested to know if any of you geniuses can tell me WHY the 64 bit version failed?

Thanks to all for the help, so very much appreciated!
Incidently

for anyone interested....
This is the second time I have spilt coffee on my laptop, the first time it happened (Feb last year!) I bought this cheap acer laptop from Tesco to use as I thought my expensive Dell laptop was toast!! However about a couple of weeks after the spill (And coffee was running through the laptop

) for some reason I turned it on and it was fine!! I lost no data, I was really lucky. So I deleted all my stuff as my teenage daughter inherited the Acer ,
This time I spilt LESS coffee. did the same again turned it off right away, dried the spill. so I am hoping that it will come alright again if I leave it be.
If it doesn't come back on again is it worth taking it to a shop to see if it can be fixed?
And yes I know with my history I should avoid having coffee around the laptop, but I am disabled and sometimes stuff happens, there is not much I can do about it.
