hmmm I thought i cleared this up with the dog icon
It's been the only problem so far the & symbol so i renamed it to dog otherwise it should work
I'm off to bed now anyway and college tomorrow so I can't really help right now.
OOO before i go an idea, It could be a registry or messenger related error eg try repairing messenger.
OR what happened to me before when i had trouble downloading any dynamic content is that there is a slight problem with IE which can affect installation, I can't remember how i fixed that error first i'd see if they can install any content at all? then try other approaches
