first of all open windows firewall. then make sure cricket2009.exe is set as an exception. then click on add ports. then add the port 9103 for both tcp and udp.
u may also want to open the ports on your router/modem firewall. to do this you need to first find out your ip adress and then create a static ip. so go to start then run then type cmd. thern type ipconfig/all. note your ip adress your dns servers and your default gateway. now open you connection in control pannel and click properties. then click ip /tcp and click properties and then type in the info there. now type the ip adress in your browser and enter username / pass. then enter the ports. the method for opening the ports may vvary from router to router so i suggest u google urs up.
