Dear Anudips, 

It happens when the former calibration is terminated by accident or abnormally. You can start a new SWATcup calibration to resolve the issue. Hope it works.

Best,

This error indicates an issue occurred while trying to edit the 8th parameter (which is Number 5 in the list). The possible causes include:

1. The mgt file (land management file) format might be corrupted or incorrect
2. The program encountered unexpected file structure while reading or modifying the CN2 parameter
3. The file might be in use by another program or lack proper read/write permissions

Suggested solutions:

1. Check if the mgt file is complete and properly formatted
2. Ensure the file isn't open or locked by other programs
3. Verify the program has proper read/write permissions for the file
4. Try backing up and regenerating the mgt file
5. If only specific files are problematic, examine their contents first

Best, 

T
