@Meenos I had the same problem, here is the updated dll file, you still need the rest of the plugin
Try replacing the dll with this one, I didn't change anything in the code, just changed the LSPDFR version and updated the .NET to 4.7.2
Seems to have done the trick for me, I haven't had any crashes since I updated it at least.
All credits go to Albo1125 for his awesome mods, I'm just trying to keep it alive a little longer and hope Albo1125 will post an upda
