Been there this weekend with a mate....try this software- I think you have the old version.pm me with your email addy and I will send you a set of known working hex files ( pure ntl).They work with this version of the software. Had no end of trouble with Version 2.02. This is version 3.0.0
PS for others havin Fun troubles.... there is a batch of iffy funs around( maybe) .Blue, with DREAM on them.... I had to erase them all before I could get any to work.Then I still ended up with 40% duff....
