Help getting past a guest feature

Bit of a long winded question here. I need to access a part of a website that is no longer available. I tried using wayback machine (needed to access it in January), but there's a problem. To get where I need to, I need to log in as a guest. I can do that no problem from the website now, but I can't on the wayback version. I figured this would be the case, but I can't think of any alternatives. Is there a way to access what I need to by bypassing this required guest log in? Or is there any other alternatives.

There are, but why do you not post the link to the address so that we could test it for you ? [Then I remember that whatever is posted here is stuck forever and the FBI raids your home to eat your bacon and cheese pizza without sharing.]
