Suddenly neural network toolbox doesn't work anymore

I worked with the neural network toolbox until yesterday when suddenly I got a error message:
At first I thougt that somehow the data I feed into the neural network got corrupted. But after checking this I could rule it out as I cause. To make sure it is not the data I tried the sample data that comes with MATLAB and I get the same error message with the sample data.
If I try to call patternnet(10) in the command window I get the following error message:
>> net=patternnet(10)
Default value is not a member of type "nntype.performance_fcn".
Error using nnetParamInfo (line 28)
Reference to non-existent field 'net_read_only'.
Error in patternnet>get_info (line 85)
info = nnfcnNetwork(mfilename,'Pattern Recognition Neural Network',fcnversion, ...
Error in patternnet (line 41)
if isempty(INFO), INFO = get_info; end
I have R2013b 64-bit. Does anybody have an idea what could be the reason that suddenly the neural network toolbox doesn't work anymore? I would very much appreciate your help.

I have the same problem. All of a sudden, Matlab NN toolbox doesn't work any more. It was fine in May.
When I was trying the nprtool and using the sample data, it doesn't work.
Anybody know what's happening? There is no source code since we are using the GUI.

This worked for me. I had another MATLAB file called mse.m in my path that was distracting the Toolbox, so I removed it.

Thanks, mse.m was troubling me too. A utility folder for another project was overshadowing MATLAB's libraries.

Thanks a lot John Malik, the problem is resolved!
