Installed the plug in, (vers 4.0.16) tested it and it worked great. Went to actually use it about a week later and it errors out with this message every time now.

Full error message: PaintDotNet.WorkerThreadException: Worker thread threw an exception ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
