ERROR - DB-270000 - Invalid String Index - Cannot Open for Read or Edit a Cell

There is one cell in my library that I cannot open, regardless if it's read only or write. It simply won't open.

Error code: 

(DB-270000): dbOpenCellViewByType: Invalid string index. 

"Would you like to open it for read"

When I open for read, it gives me the same message. But instead of an error popup, it is written as a *WARNING* in the ifcb. 

Is this salvageable?
