COACH program gave errors missing library files

I first ran I-TASSER and then COACH for a single protein (PDB ID 5lq4A). The COACH gave the following errors:

Your setting for running COACH is:
-pkgdir = /vol1/software/itasser/5.1
-libdir = /vol1/software/itasser/5.1/lib/BPOCKET
-protname = 5l4qA
-datadir = /vol1/zafer/projects/drug/data/5l4qA
-outdir = /vol1/zafer/projects/drug/data/5l4qA
-homoflag = real
-idcut = 1
-runstyle = serial
-LBS = true
-EC = true
-GO = true

run /vol1/zafer/projects/drug/data/5l4qA/5l4qA/coach/CH_5l4qA_5l4qA.pl...
cp: cannot stat '/vol1/software/itasser/5.1/lib/BPOCKET/map/gene_ontology.obo': No such file or directory
/vol1/software/itasser/5.1/lib/BPOCKET/BPOCKET/BSITES.fasta is missed!
/vol1/software/itasser/5.1/lib/BPOCKET/PSSM/BSITES.fasta is missed!

I realized that the BPOCKET folder under lib directory does not contain any subfolders named map, BPOCKET or PSSM. Below is the ls command output for BPOCKET folder of lib directory:

sysadmin@draco:~$ ls -alt /vol1/software/itasser/5.1/lib/BPOCKET/
total 45903
drwxr-xr-x 20 root root 20 Kas 17 10:39 ..

-rwxr-xr-x 1 root root 13663879 Kas 12 18:51 BSITES.bsr

That's what we get when we download the I-TASSER libraries using download_lib.pl script. I will appreciate if you can help to resolve this problem. Thanks.
