solarwinds Kiwi Syslog server

I have setup the trial version of solarwinds Kiwi Syslog server and have setup 3 devices to log to it but nothing is coming in.  I have setup my RSA manager server, My cisco Firewall and one of my windows servers.  There's nothing in the error log. How do I troubleshoot what is wrong and why nothing is coming into my server?
