Hi Lu,
I have a few suggestions for you:
1. Make sure you have write access to the temporary directory that MATLAB is using. To get the path to this directory, you can execute the following command in the MATLAB command window:
If the issue is related to permissions, you could also try running MATLAB as administrator and see if that lets you open live scripts.
2. Regenerate preferences for the version of MATLAB you are using. For steps on how to do this, please see this MATLAB answers post. Restart MATLAB after making these changes and see if you can read live scripts then. If not, could you be more specific about what you mean by it 'went dead'?
