Master Pyrochild,
Do you have a "Curves+" version which support Paint.Net 4.0 alpha? I just installed the version, and it can't be used any more. When I tried to use it, it said:
File: C:\Program Files\Paint.NET\Effects\Curves+.dll
Effect name: pyrochild.effects.curvesplus.CurvesPlus
Complete exception message: System.TypeLoadException: Could not load type 'PaintDotNet.EventArgs`1' from assembly 'PaintDotNet.Base, Version=4.0.5105.6977, Culture=neutral, PublicKeyToken=null'.
in pyrochild.effects.curvesplus.ConfigDialog..ctor()
in pyrochild.effects.curvesplus.CurvesPlus.CreateConfigDialog()
