Hi,
I am getting the below errors while registering for the exam.

Once I got security error :

"For security reasons, your session has been inactivated. This typically occurs when no activity has been detected for a certain period of time. Please start over. Return to Pearson VUE home page. "

Other time I got the below error:

"We were not able to process your payment. To continue with this purchase please select an alternate payment type or try."

Please help me with the possible solutions.
