This is a Great product! Thanks for your efforts!

I've downloaded an educational website for our children to 
be able to use offline so it doesn't cost us a fortune in 
dial up fees but we have a problem...

The site has lots of .pdf files whcih is what we want to 
use. In the instructions I told httrack to download .pdf 
files but when we tried to view them offline got the above 
error message. Searching on the net told me it must be 
a .pdf file with a .mme extension so I tried to update the 
download by intructing .mme files be downloaded too - but 
that hasn't worked. Still get the same error message.

Any ideas what I can do to be able to download and view 
the .pdf files off line? Thanks!
