default forum page a no-no

i know this may seem the lamest question ever made in this forum but i just can't seem to find the answer to it. so please help me out because i know everybody else should know the answer. so here it goes...

i installed a new style, shoe's, thanks for that , i setted it to be the default to every member, on every forum, and it did that, but i can't seem to get rid of the default forum page, the very first page, when you load the forum and you're not logged in, it's always the same default of vbulletin. only when i click on some link it switches to the new style. how can i get rid of this?

thanks for your help
