Unfortunately, I know that others have had the same problem. Nige couldn't post here for the longest time but I know that he can now cause I've seen his name. Also Jenn can't access the site at all either - Becky is posting stuff for her in the PIF forum.
I think it would be a setting issue but I know that Peter worked with Nige and they couldn't figure it out.
I know this doesn't help - except maybe to know that you are not alone
