Product Code

When I completed the initial registration during SanDisk installation I entered the wrong Product Code.  I entered D08G instead of 008G.  I did not receive an error message.  Please let me know how I can correct this.  The numbers are so small.  Partially it is my fault due to becoming farsighted from old age.  I even put reading glasses on to read the code and I still got it wrong.  When I went to read the code a second time I realized I made the error. 

if you didnt recieve an error i would not worry about it. sandisk will know what it is suppose to be. what you entered is the part number. you can always contact sandisk 866-sandisk and they can help you if you need to.
