Comsol v4.1 in client/server mode -> issue with saving files

Dear all,
from my local Linux machine Comsol (v.41) is connected to a remote Comsol Windows server (v4.1 as well).
I want to run fa model from a Matlab script, that I start from my local machine and that is executed in client/server mode on the remote machine.
When running the script on the remote Windows machine directly, it runs without any problem.
When I run the script on the local machine, the remote one is busy for a long time (checking the task manager performance monitor) and the model seems to run completely with no problems as well.
But when the script wants to save the results using model.result.export('datax').run, an error message appears, saying something like "made 5 attempts to write the file, giving up".
The script should save the files on the local machine, not on the remote one.
But I also tried to save on the remote machine, and it did not work, too.
Did anyone experience something similar and found a solution for this?
Is it an incompatibility issue between the windows and linux version of Comsol?
Thanks a lot and best regards,
Juergen

Update:
Saving the model file itself using the "model.save" command does work!
It is just when I try using the model.result.export('data1').run command, which does not work and throws the following error message:
Any ideas?
