Dear Members,

I am getting this error in SWAT+ Editor when I try to run the model:"Unable to update input files directory."[screenshot attached].My simulation period is 1984.01.01 to 2013.12.31

My project path is on C: drive and the Scenarios/Default/TxtInOut folder does exist. I have tried closing all files and running as Administrator, but the error still comes. I have attached my wgn files with this email for your reference. Please let me know how to fix it.

Thank you very much for your consideration.

Best regards,
S.D.Wittachchi
