I've build K2 workflow with Microsoft Visio, every shape I've done to "bind to workflow". but when I test my workflow on sharepoint there's error
"An instance of the Drawing1Page 1 workflow could not be started. Review the event viewer for detailed information"
there's no information where the error located, so I try to "Unbind from workflow" every shape in visio, then I try to repeat binding shape to workflow, but this error always appear, until I restart my PC...

huff it's waste my time...

StackTrace: at Microsoft.Office.Interop.Visio.IVLayer.Remove(Shape SheetObject, Int16 fPresMems)
at SourceCode.Workflow.Visio.K2.UpdateK2DataObjectLayerLines()

please help...
