powerstore 2 authorize.net checkout issue

Information is not being sent to the authorize.net gateway site when a sale is made on the http://lamppostsonline.com/
I have been checking with authorize.net and the Login and tran_key are correct but the sales are not being forwarded to their site, so no error messages are being generated. I do have sales recorded in the powerstore admin and customers (we didn't realize existed) recieved receipts.
The problem was brought to our attention by a customer who used the shopping cart was inticated that the sale was completed but did not reecieve a email conformation. His sale was not recorded by powerstore, I don't know if this is an indicator of an even larger problem than the gateway not receiving the info (as if that isn't enough).
I believe the same issues probably exists with http://outdoorlightingfixturesonline.com/

Any help with solving these issues would be greatly apreciated
