Script to connect to Paypal does not work. :(

[shawnG]

Some guy that I had a falling out with a while back and whom is more experienced then myself wrote this script on Paypal a while ago. When in place and working, it does not seem to work and pulls out this error :

 

Array ( [TIMESTAMP] => 2010%2d02%2d04T02%3a43%3a42Z [CORRELATIONID] => 40a34e5a4b98 [ACK] => Failure [VERSION] => 51%2e0 [bUILD] => 1179072 [L_ERRORCODE0] => 10002 [L_SHORTMESSAGE0] => Security%20error [L_LONGMESSAGE0] => Security%20header%20is%20not%20valid [L_SEVERITYCODE0] => Error ) SetExpressCheckout failed:
