Hello and thanks for all the help, I have kinda sorted it, All i did was re-install java runtime SE and it worked fine But low and behold java wanted to update so i did and it no-longer worked So i uninstalled the update and bingo it works again....Hope this helps the many people with the same prob

Yeah, I was having problems, and being doubtful that it'd work as I'd tried dozens of these things, but it's sorted. I'm in a good mood. Thanks, guys
