I-TASSER 2.1 Standalone issue--Need some help-Thanks

Hello Admin:

I am using the latest version (2.1) of ITASSER (& the template library files). I am running I-TASSER in
parallel mode in Linux cluster (with Ubuntu OS).
----------------------------------------------------------
Linux fr-s-head-1 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
----------------------------------------------------------------------------
I had successfully installed/used the previous version of ITasser in parallel mode with no issues.
This time, I am having some issues.

The err_IT_wMUSTERmod (see below) contains several lines of "cannot open protein". The modeling seems to
run and I do not see any other errors. The latest set of output files that I see are:
np_47sim_1A
....
np_47sim_10M

Can someone help me identify what might be causing this error?

Thanks very much

Ravi
