Don't worry, a lot of errors happen when customers confuse the letter O with the number zero or vise versa. The same goes for the letter I (lower case i) and letter L (lower case l). So, to eliminate any errors copy and paste is the best way to enter your unlock key and to send us your correct product registration code. After receiving your unlock key from us run the program you purchased (open the registration window if not open already) enter the unlock key by copying and pasting it. But before you click enter to register the product, make sure there are no empty spaces in front or after the unlock key.  Take this unlock key as an example  " DRT5YTH86JGU " In front of the letter " D" and after the letter "U " are empty spaces and those will cause our programs not to accept the key to register them. Here is how it should look when you copy and paste the unlock key the correct way "DRT5YTH86JGU". There are no empty spaces in front of the letter "D" or after the letter "U". The program will now accept the unlock key, assuming you have sent us the correct product registration code and you are using the latest version of the program you have purchased.

Let's recap what we just discussed.
Always copy and paste to eliminate typos.
