Q1: I purchased a registered version in the past, but I have lost the serial number. How can I get my serial number back ?
Q2: I have recently reinstalled/replaced my PC, but I do not have a CD, or I have lost my CD, How do I install the latest version ?
Q3: I have purchased a registered version and I have got the serial number, but when I enter it the program told me it's not valid, what's wrong?
A3: Since the serial number is generated from Your Name and Company Name, so you must type them EXACTLY as printed on the invoice or email. Space or case is not significant, but all other characters must be typed. A serial number is only for one software, so please make sure you are entering the serial number for the specific software.
