I'm having the same problem, orders won't post in ZC. I have not had ANY post for me, ever, so it's not intermittent for me like some folks have said for theirs. New install of 1.3.7, patch applied from the 21st with no improvement. DrByte, I PM'd you my log. I note that my log stops at Breakpoint 1. Other people here have more info after that. Clue?
