For anyone interested, I found out how to get PMG working again.

1. Open "Flash Player Debugger.exe".
2. On the top left, open the View menu and choose Quality. From there, select High.
3. After this, return to the top left and select "File". Select "Open", this will open a pop-up window.
4. In this window, choose "Browse" and go to where you downloaded the PMG SWF files. Double-click on one of the files, then click "OK" on the popup.
4. Now you can enjoy PMG-ing offline in HD.
NOTE: After you have opened a PMG file once, it will be in a "Recently opened files" list at the bottom of the menu that opens when you clicked "File" in step 3.
If you open both files once, they will be available straight from the menu and you can skip most of step 3 and 4 next time.
