I am not able to make payment ,Please send papal request for perpetual license.
What exact error are you getting? I can see other people were able to purchase and so it should work for you too.
Payment for Stockalyze is handled by 2checkout and it supports paypal as well. I am sure you can pay using paypal as well. Please give it a try again and let me know if you face any issue.
