Thank you the recommendation, I just submitted a ticket to Camelot. I want to state the issue I am have so that as soon as it is resolved I will post the solution, this is in an attempt to save someone with the same issue time in resolving the problem [because of this ongoing issue hdworkgear is essentially still broken since the server melt-down, now day 10]:
Since the server come back PayPal [PP] has not been able to communicate with my admin page, PP is able to captures the cart and customer payment information, but when the customer confirms the order an error messages occur: 10415 and 10002/API Security Incorrect. PP does capture the payment, but there is no record of the transaction recorded at the admin page. The customer is informed that an error occurred and instructed to refresh the page.
After numerous calls to PP and installing new API credentials at the payment module and tweaking my email settings, same errors continue to show, PP claims the problem is on the server side?
if PP captures the payment, then there is no question that the problem is on the server side. PP got you your money, they send back something, and now your host/ZC is having trouble processing the return string. for whatever reason....
a 10415 means a duplicate transaction. search this document for 10415:

it is possible that when the customer receives the first error, they refresh the page, which resubmits the order resulting in a duplicate transaction.
a 10002 error is far more generic, and looks to be a problem with security credentials. although that is tough to tell....
good luck!
