Please help my work for 8 months won't open.

[Mr. Tender Chess]

This error code is showing when I try to open my work in character animator

• , "(2061843879:386+24) table index is nil". 

My whole work for 8 months. Please help. I don't have any back up.

Then I traced and discovered it has to do with my ROPE File. Please help me.

Thanks.
