PACK15NISSAN:
First, let me introduce myself. I'm Frank Steele, the guy who wrote Trax.
Having read your thread, I'd like to give you my take on it.
First, you are trying to sell your software. I would STRONGLY urge you to reconsider this. When people give you money, you have an obligation to them. This includes people that mess up the software by removing the password, delete formulas, and then send you their software and expect you to fix it for them. This includes people who won't read the instructions and e-mail you, expecting you to be their sole-scource private tutor.
