You have to be a registered user to access their forum, I believe. If that is not the problem, I have had the following occur with other programs. If, for example, I typed in the incorrect registration number, it didn't want to ever accept the correct one. I have never had a problem with the Vue forum on e-on's site. I use IE 6 on all my machines and can access it from anyone. I don't know if this is helpful, but IE 6 has always workd for me.
