Paypal IPN no customer address details after an upgrade

heeeeellllllp!

for some reason I am no longer getting the customer address details via the Paypal IPN.

I am guessing it is something I have done as I have updated the cart to v1.371 and eerrrr must have broke something.

I enabled the debug mode and the 'keys for submission array' appears to be sending the info ok but paypal has a problem and says no address details supplied when I log into my Paypal account to check the buyer details.

Anything else I can try?
