run hanged at threading MUSTER

Hello,

I'm trying to run I-TASSER locally but I'm having some difficulties.
I am testing 3 different sequences simultaneously, using the "parallel" runstyle and the "light" mode.
For two sequences the run seems hanged at the same point:

"1. make seq.txt and rmsinp
2.3 run solve
2.4 run pairmod
3.1 do threading
start parallel threading MUSTER"

It is stopped here from Friday afternoon.
For the third protein (1ic9) , very small (around 30 residues) , it seems blocked at a different point:

"1. make seq.txt and rmsinp
2.3 run solve
2.4 run pairmod
making sequence filemake msa.aln file
2.4.1 removing homology templates based on and 1
2.4.2 running pair ................
FORTRAN STOP
3.1 do threading
start parallel threading PPA
start parallel threading dPPA
start parallel threading dPPA2
start parallel threading sPPA
start parallel threading MUSTER
start parallel threading wPPA
start parallel threading wdPPA
start parallel threading wMUSTER"

Any ideas?

Thank you in advance!
