Order confirmation mail doesnt parse the CUSTOMERNAME, etc codes

Hi again

Since I couldn't find a thread on this problem i'll start a new one.

I did some test orders with Marketpress and everything is working fine except for the COSTOMERNAME, etc codes in the New Order and Order Shipped settings. The emails get sent but the codes aren't parsed, still says CUSTOMERNAME, ORDERID, etc in the recipients mailbox.

It's a fairly standard wp mu install with a couple of sites. Have you seen this before or do you have any idea what the problem is?

Thanks!
