Problem with torque when running I-TASSER 3.0

Hi, I am using torque client 11 in ubuntu 14.04 x64. When I run I-TASSER in parallel mode, I get this error at threading time: qsub: No default queue specified. I have installed torque by this instructions: http://www.installion.co.uk/ubuntu/saucy/universe/t/torque-client/instal...
I have corrected local host name and qsub and qstat paths in runI-TASSER.pl script. I even have added -q default or -q urgent in the line but the errors continues. I appreciate if any body can help?
