Do you have a link where this can be seen at? It seems that you are doing things correctly if you have entered your account details into the globals file and are testing it properly. What is the result you get if you attempt to run a credit card transaction?
When you get the error message about the transaction not being completed what page are you on when you see this? Have you checked on the test mode setting in the globals:
$WAGLOBAL_Test_Mode = false;
You must have the test mode set to false in order to test transactions.
