MATLAB: Can’t save workspace of 3 month calculation – URGENT

MATLABsave workspace v7.3urgent

Hi,
I did some scientific simulation on a university server which took more than 3 months. The result worked out great. I wanted to save the workspace so I could continue analyzing on a local machine…. but I can't figure it out!!
I tried
save('data.mat');
which returned
Warning: Variable 'image' cannot be saved to a MAT-file whose
version is older than 7.3.
To save this variable, use the -v7.3 switch.
Skipping... 
Warning: java.awt.Robot[ autoDelay = 0, autoWaitForIdle = false ]
is not serializable 
Error using save
Can't write file C:\data.mat.
then I read about v7.3 option and tried it like this:
save('data.mat','-v7.3');
which gave me
Warning: java.awt.Robot[ autoDelay = 0, autoWaitForIdle = false ]
is not serializable 
Error using save
Can't write file C:\data.mat.
Now I'm at a loss. I really need this data and I can't affort to have to run the 105 days simulation again! Please help me save this workspace somehow. Estimated size is just one GB.
kind regards, Arnold

I found a solution. There were some variables which were of class 'java.awt'. I deleted them since they don't contain anything I need.... and now it works.
Panic-attack over :)
I wonder why I have to set the parameter 'v7.3' manually in the save command, why isn't it standard?
thanks
