Blender SMD Plugin Problem

[jugol]

I really hope I am posting this in the right place so if this is the wrong place, please move it to the correct 1.

I have no idea what's going on but for some reason, my Blender Source Tools Plugin has suddenly stopped working. I don't know if it's something I've done but all I do know is now it's not working. Basically I've tried to reinstall the plugin via the user preferences but when it comes to ticking the box to enable it, I get an error message. I've screenshot the error and also included a screenshot of the same error from the Command Prompt.

Any ideas what I need to do to fix it?

It's a syntax error, that line in the code has a wrong character and the code can't be read at all by Blender. Don't know how this happened, but I checked the plugin in my own computer and that ':' should be an '='. Do this:

- Close Blender

- Open the file mentioned in the log with a text editor:

Code:

C:\Users\pcuser\AppData\Roaming\Blender Foundation\Blender\2.79\scripts\addons\io_scene_valvesource\__init__.py

- Search for the line that triggers the error:

Code:

ob_type : StringProperty

Change the ':' character for an '=', save and restart Blender.

Let me know if this solved the problem.
