Several months ago I downloaded an ibpfree forum using these instructions:

<http://httrack.kauler.com/help/CatchURL_tutorial>

The forum wasn't too big (some 550 MB), and when the download finished i tried
logging in (it was one of those forums where you can't access any page without
logging in), and to the best of my memory, I succeeded. I stored the forum on
my backup partition and forgot about it. Since then, I switched from XP to
Win7.
A couple of days ago ipbfree forums went down, permanently. They say nothing
will be recoverable. Needless to say, I was glad that I downloaded the whole
thing some months previous. 
However when I tried to access it this morning, after typing in the user name
and password, it directed me to the web page online, which naturally doesn't
exist anymore.
How do I access the thing on my hard drive?
