I recently installed R2013b. Ever since I get the following error (see image). This happens whichever way I try to open the file (while matlab is off, within matlab, even typing edit won't work). Another thing I tried, I opened a script with notepadc++, copy-pasted to a new script in matlab, everything runs properly, save it, close it, reopen it and still get the error. Do you have any clue how can I get rid of this nuisance?
