Yes, It took a while to work out why only my computer wouldn't work..We all have one each..The others got onto the internet using the wireless connection and mine didn't..
Then we realised the last thing we did was download the upgrade I think it was IE 8..
Thank you for trying ellen..
My son tried to download a new windows explorer up grade, it was vista and not computable with my machine and completely wiped my windows out.
I couldn't get on the internet so he had to install Linux and wipe windows from the machine altogether..
