I have spent all day creating an excel linked sankey flow diagram, which was working fine. I saved my work and quit out of both programs and now when I try to reload the file I was working on I get this error before program quits: "System.NullReferenceException: Object reference not set to an instance of an object."

Can someone please espying what has happened and how I fix this?

Hello user33,

sorry to hear you are having issues when trying to open the file in e!Sankey. Is this in e!Sankey 3 or e!Sankey 4? Are you using the latest version ( or respectively)?

I suggest you send the log file to the e!Sankey Help Desk ( I am sure we can fix this issue. You can access the log file via Menu Help > About or browse directly for the file 'general.txt' at
C:\Users\<USER>\AppData\Roaming\Ifu Hamburg GmbH, Germany\e!Sankey\4.1.1\log\. The information in the file will help to analyse what caused the error.
