Traceback Error when trying to reopen results file

[bhavana-docking]

Hello,
I am having a traceback error when trying to reopen a results file. I docked the protein and ligand successfully and I got an input file in the format of .amdock file. However when I try to load the data and open using the analyze results feature I am getting the error that I have pictured below.

Can I please get help on how I can clear this error and be able to open my results again.
