UPDATE:
ok, so it seems as though i've been able to move on to another problem. I no longer get the timeout error that I was getting, but now I get this response:
" There has been an error processing your credit card. Please try again."
The order is getting processed and the cc is getting charged, but zc doesn't "see" that this has happened.
I'm using the Authorize.net (SIM) payment module. Thanks!
