Your CSR has a CN value of:
qbms.compressportusa.com/emailAddress=emilio@benamorgrp.com
Here's the complete line from your CSR:
Subject: C=US, ST=Florida, L=Miami, O=CompresSportUSA, CN=qbms.compressportusa.com/emailAddress=emilio@benamorgrp.com
There are two problems with this:
As the error says, it's not in applogin:hostname format. The CN must have the format applogin:hostname. e.g. it should probably be something like: "qbms.compressportusa.com:compressport.com"
Intuit's appreg tool is broken, and borks when you include an e-mail address. Do not include your e-mail address when you generate the CSR. If you enter your e-mail address, it will not work.
There's a bit more detail on this process and some common errors on our QuickBooks integration development wiki.
As a side note - it's a heck of a lot easier (at least for test/development purposes) to get set up in DESKTOP mode instead of in HOSTED mode. Might be something to consider, at least until you're ready to go live.
