That is what I found on Mirus site. Have you ever experienced problems using firewalls, antivirus etc?
"Firewalls, AntiVirus and AntiSpyware
Zen-Fire is an intense trading engine. When connected, your computer rapidly receives large amounts of data. Software such as Firewalls, AntiVirus and AntiSpyware have a tendency to see this stream of data as something that could possibly be bad for your computer and may end up blocking out parts of the data or the entire connection. This can result is orders not getting filled, inaccurate price reporting and disconnects. We recommend turning off all active protection from these programs before connecting to Zen-Fire and during trading."
