Error message " Your library files are not complete, please download library with the script download_lib.pl"

Dear discussion board,

As my network proxy is configured with squid cache, so i downloaded the i-tasser library files manually and decompressed them in a directory (libdir) of the i-tasser package.

After running the perl script - ./runI-TASSER.pl, i am getting the following output:

Your setting for running I-TASSER is:
-pkgdir = /home/bif/Desktop/I-TASSER4.4
-libdir = /home/bif/Desktop/I-TASSER4.4/
-java_home = /usr/share
-seqname = seq.fasta
-datadir = /home/bif/Desktop/I-TASSER4.4/s
-outdir = /home/bif/Desktop/I-TASSER4.4/results11/example
-runstyle = serial
-homoflag = real
-idcut = 1
-ntemp = 20
-nmodel = 5
-light = true
-hours = 6
-LBS = false
-EC = false
-GO = false

Your library files are not complete, please download library with the script download_lib.pl.

I also tried the script download_lib.pl, it stays unresponsive. I am new to protein modelling .please point me towards how to resolve this issue.
Thank you in advance.
