I can not activate my test engine/ the authorization codes shows error, what is the problem?
Please do not worry when you meet such problem. In fact our test engine authorization code is valid only once, so when you try to activate or download the exam for the second time you will meet authorization error. Please contact us and tell us your order number. We will reset the authorization code for you. In fact the authorization code will still remain the same, but we have reset it, so you can activate the exam.
