['Portable Document Format' FileType Plugin (.PDF)]

I am unable to use this plugin due to error message mentioned several times in this thread.
Error message:

Exception:

 

System.FormatException: Input string was not in a correct format.

   at PaintDotNet.FileType.Load(Stream input) in D:\src\pdn\src\Data\FileType.cs:line 512

System:
Windows 10 Pro: 19042.746
AMD 5800X, 16GB RAM, GTX 1080

It used to work fine, but stopped after I reinstalled Windows to newest version.
Tried:
1) Ghostscript 9.10;9.26;9.22;9.53.3 (always removed the entire folder after uninstall finished)
2) Running different Paint.net (4.0.16;4.2.15)
3) Moving plugin files around. The .txt file attached to plugin says to, quote:
Copy the two files OptionBasedLibrary vX.X.dll/.dlc to the Paint.NET\ folder (NOT to Paint.NET\FileTypes\ !!!)
While some forum members claim that you have to put it in FileTypes. PS. both produce the same error.

I have the exact same setup at my office PC, which runs Win7 and the plugin works fine there. (ghostscript 9.22, PaintNet 4.016) This would point to Win 10 as a culprit. Any support would be much appreciated.
