Firewall Question

I have a wireless network that I use at home.  It is a basic Linksys wireless modem that I use (if you need the specific model number I can provide it).  I have the same applications on my desktop and my laptop computer.  The application works fine on the laptop which has the Windows firewall disabled and no other firewall present, but I have problems on my desktop which does have a firewall enabled (McAfee).  The applications connect to servers to verify my license is valid before allowing me access.  

I right now I use both machines in tandem to do what I need to do but I would like to use one.  What should I do to resolve this issue?  Would I put myself at a greater risk disabling the McAfee firewall and only using the firewall on the router?

Yes the application server is outside of my network.  I have not configure McAfee to specifically allow ip's or ports.  I just gave the application full rights so that it can send and receive data from the application server.  I'll have to check and see if that is an option and how to do it.

Absolutely.  I have found that just allowing an application privilege is not enough with some firewalls.

McAfee apparently pushed out some updates to there security center between the time I posted this question and now all my applications work again.  Thanks for you guys help.
