Prallel Computation, CentOS & Ubuntu file versions

Hi there,

I'm using Yade trunk on my computer on Ubuntu. Recently, I installed Yade trunk on our cluster computer which runs on CentOS. I ran a simulation model and I saved it as *.yade file with the cluster computer.
The problem is I cannot open this file on my PC. I got the following error:

bemaj3@GCI-REGAL-ETU5:~$ yade2014-04-22 loader.py
Welcome to Yade 2015-04-02.git-799b1b5
TCP python prompt on localhost:9000, auth cookie `cksuas'
XMLRPC info provider on http://localhost:21000
Running script loader.py
Traceback (most recent call last):
  File "/home/bemaj3/sw/bin/yade2014-04-22", line 182, in runScript
    execfile(script,globals())
  File "loader.py", line 1, in <module>
    O.load('settled.yade')
RuntimeError: unsupported version

Why this happens and how can I solve this problem?
Thank you.
