That was the first thing I tried, placed the cracked passwords into a file
and added it to the password list in LC5, removed the other lists just to
make sure it was working but it didn't make any difference, it was like the
dictionary attack didn't see the numbers or characters. I tested it a few
different ways and there was not change in the completion time.

Seems totally logical that it would work but each time I tried it I came up
with the dictionary attack taking the same amount of time to complete..
