I have tried uninstalling and reinstalling plugin and updating all the settings but still receive an error when trying to validate the CC information.
System.TypeLoadException: Could not load type 'Nop.Web.Framework.Validators.MyValidatorExtensions' from assembly 'Nop.Web.Framework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null'.
