Hi Michael
I have unlocked the classes for you.

for the order, we appreciate the support.
If you were logged in and the classes did not unlock, then check next time after you have finalised your payment at 2Checkout, that you click the orange Finalize button. It will often give a "security" warning when you (as you are moving from the encrypted payment area back to our non encrypted website. If that does happen just click okay / continue. (People often take this warning as a problem, but it is just a notice and perfectly okay to continue)
Check for that next time and let me know if it happens again
