HI @Anonymous,
It has been a long time since I worked with that file but I believe that the attached CTB file should work with it.
If you double-click the file, it should open in the Plot Style editor. I like to use the form view tab to edit the settings.
The first thing I did was to select all the colors in the left hand window and then assign them to Black in the properties Window. I also select Screening of 100%.
The next step is to now create exceptions to these settings. For instance, pen 15 I like to use Color 252.
You can then select each individual color on the left and assign them a standard lineweight on the right in Properties.
I believe that this CTB file uses 4 different line weights.

Please select the Accept as Solution button if my post solves your issue or answers your question.
