what do the debug emails say ? if debugging is on and there are no emails then ZC is not being hit in the correct spot by worldpay. First way to test this is to put an order through and then hit cancel at worldpay and see where it sends you.
There is also a massive time lag between setting up things like passwords at worldpay and them finally being sent through, we have one guy above that took 24 hours for their system to update all of the while when worldpay tech support claimed it was the module not working. The guy made no changes to the module and suddenly worldpay started to send through the info.
I find it quite odd too. For one thing Zen Cart themselves have to submit the whole shop and I asked Dr Byte to do so last year when the big hole was fixed, but also worldpay will not give me an account for development, and since I don't want to pay their charges for an account that I don't use I an stuck having to borrow people's merchant id's if I need to teset anything.
