Please help!
I've got a problem using the PayPalPaymentProvider, with an error that is thrown when PayPal tries to return to /checkout.aspx. Everything seems to work fine until that point. The error in the log is as follows:
System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

The error message gets cut off there. It looks like an issue of an invalid SSL certificate, but the cart.aspx page is initally called under HTTPS as well, and it loads just fine, so doesn't that mean the SSL certificate is fine?
One additional thing I've noticed is in that second-to-last line where it says the file is in "d:\Inetpub\wwwroot\shopdev\Store...", but I've moved the site. It is no longer in "d:\Inetpub\wwwroot\shopdev\", but is instead in "d:\Inetpub\wwwroot\live\". Yet the error message is still referencing the old folder. Could that be part of it?
Any help is greatly appreciated!
Thanks!
