I have only just found and joined this forum and am now browsing past posts; hence the delay in replying to you.

My advice fwiw is that there's nothing any one programmer can do which can't be undone by another who is at least as good. However it may take time.

Suggest you contact a second-year Computer Science student forum at a good uni and plead the damsel in distress bit. If one hacker got in so can another, and sort it for you. Challenge their egos. Be aware though that whoever does it will be spending all his free thinking time on your problem until it's cracked.

Good luck,
