Yes, every single transaction has been forwarded to your system (they all are listed under "View/Download Transaction Log").
The test-products I set up both are priced "0.00", so I guess that doesn't have to do with Paypal at all.
The purchase emails sent to the buyer work perfectly, by the way.
It's just the sales notifications for the seller, that don't make it through.
Any other idea?
If no, is there a way to reset my account? I got the feeling that it's a bit "buggy" anyway, because I twice had the problem that my password wasn't accepted, so that I had to generate a new one.
