First of all can I thank everyone for your help.
I have cleared cookies, checked java and explorer are up to date, installed microsift essentials and also defrag my computer……cant think of anythingelse to do now!!!
I have been having this problem for a week now and dont get it anywhere except when I attempt to get into JC Chat and as you can see I can still access the boards.
Not sure about the next move but thank you anyway xxx
