The error message is saying the cancel and return URLs are not correct. They are being passed as:
http://www.kamicreations.compp_confirm.php
http://www.kamicreations.compp_cancel.php
The "/" character is missing the domain and page.
double check in the WA_Globals.php page the the $WAGLOBAL_Root_URL variable ends with a "/", for example:
$WAGLOBAL_Root_URL = "http://www.kamicreations.com/" ;
