Problem running I-TASSER

I have installed the I-TASSER program as per instructions and when I try to run the program I get the following error:

xxxx@bioinfo1 ~
$ /home/xxxx/I-TASSER/I-TASSER2.1/I-TASSERmod/runI-TASSER.pl -libdir /home/xxxx/I-TASSER/I-TASSER2.1/ -seqname Zhaoying_TCR_Beta_Subunit -datadir /home/xxxx/data/Zhaoying_TCR_Beta_Subunit -usrname xxxx
Your setting is:
-libdir =/home/xxxx/I-TASSER/I-TASSER2.1/
-seqname =Zhaoying_TCR_Beta_Subunit
-datadir =/home/xxxx/data/Zhaoying_TCR_Beta_Subunit
-usrname =xxxx
-runstyle =serial
-idcut =1
-ntemp =20
-nmodel =5
cannot make temporary directory

In my tmp directory there is the following:
xxxx@bioinfo1 ~
$ ls -l /tmp/xxxx/
total 0
drwxr-xr-x+ 1 xxxx None 0 Jan 14 10:37 ITZhaoying_TCR_Beta_Subunit
xxxx@bioinfo1 ~
$ ls -l /tmp/xxxx/ITZhaoying_TCR_Beta_Subunit/
total 0

Any assistance to get around this error would be appreciated.

Another question, would I-TASSER run on the windows platform through cygwin?
