Any idea what is causing this?
I'm pretty sure the vendor name I'm entering via the admin of my zen cart is correct, but what password do I need to enter?
The password I'm using is the administrator one SagePay issued me with when we set the account up.

PLEASE HELP!
Hi apovey, this sounds like you have entered the wrong password into the admin side of the payment module.

Before you use the module it sets up automaticly to use the simulater, the password for this will only be shown to you after you first try to use it, its shown on sagepays site that you are taken to.

If your going for test mode then the password is the encryption password that SagePay have supplied you with amongst your paperwork. The administrator password is for when you log in to your sagepay admin on their site.

Hope this helps
