No License Agreement?

I purchased a CD containing multimedia graphics and such.  I was
looking for the license agreement to see what my rights are in using
them.

Is small print it tells me that I can find their licence agreement on
their web page.  The only problem is that they don't seem to own the
domain name they've given anymore, and the number they've supplied has
also been disconnected.

It looks like this company went under, but I don't know how to verify
that absolutely.

They didn't supply their license agreement with the CD, they no longer
own their website and the number that they've given has been
disconnected.  

My question is this:  Since they have provided me no reliable way of
getting my hands on this licensing agreement, does this mean that I
can't be held to the terms of any licensing agreement when using this
product?
