Path issues, java crashes and psychtoolbox woes!

So a few things to consider I know, and I appreciate you even clicking on my thread.
First, I am running R2011a (7.12.0) on windows 7. It is installed on C:\ which I do not have access to change (restricted defence computer). My desired working directory/path is in 'my documents', to which I have full access.
I am having troubles with paths, often when I restart Matlab my paths are gone and I have to add them again. The default goes back to /system32, a dangerous place to be writing/reading from unnecessarily (were that I could even write to the C drive).
I have tried the userPath and file>set path methods, neither seem to be effective. I cannot have a startup file saved into the install directory nor can I specify 'start in' parameters due to restrictions accessing the install directory and program properties respectively.
The pathing issues (I assume) force me to run the psychtoolbox setup every time I restart. Which is a major pain.
The event that triggers the reset on the pathing is usually a java error, I get a recurring set of red lines and have to force close Matlab.
Here is the error:

I appreciate any advice, and apologise for my lack of clarity if that is the case.

Get your system administrator to put the appropriate startup file in place. You do not need to do it yourself: you just need it to be done.
