I got an error while opening K2 Designer for Visual Studio. It looks like: Package Load Failure. Package 'SourceCode.VisualStudio.WorkflowPackage, SourceCode.VisualStudio, Version=4.0.0.0, Culture=neutral, PublicKeyToken=16a..........' has failed to load properly (GUID = {..................}. Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future?.........
