COFACTOR on server - error message check_email and max_job_num

Hi,
I'm trying to run COFACTOR on the server and received an error message:

107 if email in email_unlimited_dict:
108 max_job_num=email_unlimited_dict[email]
=> 109 if ip_pending_job>=max_job_num:
110 print "ERROR! There is already %d job pending from IP address %s."%(ip_pending_job,ip)
111 print "Please wait 30 minute before submitted jobs from the same IP."
ip_pending_job = 0, global max_job_num = 1
: local variable 'max_job_num' referenced before assignment
args = ("local variable 'max_job_num' referenced before assignment",)
message = "local variable 'max_job_num' referenced before assignment"

I don't have any other job running on the server at the moment, and I tried with lab internet, home internet, and wifi hotspot (using the same computer) and still get the same error message. Any advice please?

What I'm really trying to do is to do structure alignment of model 2 from my I-TASSER output (there's a specific reason I want to try this). Is there other way to do this?

Thank you
