OmniMarkupPreviewer 404

Hello,

When I open OmniMarkupPreviewer on Firefox, this is displayed:

Error: 404 Not Found

Sorry, the requested URL ‘http://127.0.0.1:51004/view/31’ caused an error:

'buffer_id(31) is not valid (closed or unsupported file format)'

**NOTE:** If you run multiple instances of Sublime Text, you may want to adjust
the `server_port` option in order to get this plugin work again.

I have Python 2.7.6 This is what it says in the console:

OmniMarkupPreviewer: [INFO] Launching web browser for http://127.0.0.1:51004/view/31
OmniMarkupPreviewer: [ERROR] Exception occured while rendering using MarkdownRenderer

    pairs = [x.split("=") for x in ext_args.split(",")]
    File "./markdown/__init__.py", line 234, in build_extension
  UnboundLocalError: local variable 'module_name' referenced before assignment

Please help!

I faced this today, just change the port, it seems another server is already using it. Go to Preferences -> Package Settings -> OmniMarkupPreviewr -> Settings - User and change the port:

{
    "server_host": "0.0.0.0",
    "server_port": 9998
}

that should work.
