Chet,
As you pointed out, AC is very fairly priced, and short of a free product like PF, you can't get an EMR for anything close to this price. So if they tell you "two licenses and two supports", then you are still doing well. On the other hand, Jon B. and the company have a reputation for being generous and fair about this stuff. I would call or send an email to convey the relevant facts and ask for help. You are talking about one person seeing patients, one person doing notes, one person signing notes, one version of the program, and one e-prescriber. You have paid for two licenses; maybe they will give you a deal and allow one annual support.
