I have 2 IGT Game King poker machine, I installed Tito in both, the first one was no problem and works great. The second machine I am unable to get it working, when I configure it as instructed by the Tito sheet and YouTube Video it will not print out a ticket. It says HANDPAY REQUIRED CALL ATTENDANT. I've tried reprogramming several times but still not working. What I have figured out is when I switch the validation setting back from system as required by the Tito instructions to standard it will then print out the ticket, but it won't work in the machine as the ticket has a bunch of numbers where it should be all zeros. Thank You For any Assistance with getting this problem resolved.
