I've lost all information used when purchasing the program.

Answer:

Regretfully, we cannot help you update the program if you remember no or little information. E.g. if you can provide with your name only (John, for example), we cannot help you. There are hundreds of Johns in our user database and we cannot provide you with their personal details, as this violates our Privacy Policy.

Please provide us with more information, for example your last name, several email addresses you used at the time of purchase, the approximate date of purchase, etc. This will help us identify your account.
