PayPal via SagePay Direct

Hi,

Has anyone implemented Paypal via SagePay's Direct method?  I'm in the process of trying to do this but I'm having an issue with the configuration on SagePay test environment.

I've created an merchant account using PayPal's sandbox.  This has also generated an email address for the account.  When I try to use this in SagePay's test environment it tells me the email is not a valid support email.

I've emailed SagePay support about this a couple of days ago, but I've had no response.

Has anyone else come across this issue?

Regards,

Alex.

An update: SagePay came back to me and it turned out there was some configuration required on their part.
