Create button, when pushed, does nothing

Hi, I had a terrible experience with support. I called twice and spoke with different people, both told me the reason that I could no longer create a new html file was b/c I needed to update my operating system. I broke down and did this, as well as updated my application to the latest versions. It limited my plugins, and denied access to systems that are no longer compatible with the updated system. AND STILL, I cannot create a new file. I am beyond frustrated.

If anyone knows why I am unable to create a new html file, please let me know. The create button, when pushed, does nothing.
