Further Notes:
When buying a program you are automatically registered, and a cookie is placed on your computer.
This saves the hassell of logging in each time you use the program.
However if Paypal didn't redirect you back to the site, or the cookie changed, or got deleted, then the program will not be activated.

However you can reactivate it by using this form, or the original activation link that was emailed to you

This will reactivate your calculators to the original timescale.
So if you had 3 days left, this will reset those 3 days.

However if you have never purchased a calculator, or your original activation has expired, you will get a notification of this.

Your 'User Name' is the same as your Paypal 'first name', or the 'first name' you gave when purchasing with a credit card, or the user name you gave when purchasing.
Your E-mail is the same as your PayPal email, or the email you gave when purchasing with a credit card, or the email address you gave when purchasing.

If you don't have those, the 'user name' and 'email' is also shown on the original email you received from
"". when purchasing the program.
The original activation link will also reactivate a lost activation.

If all else fails, please contact me through the 'contact' menu.
