Ghost explorer can't access to .gho file

I have Ghost backup with 46 files. 

I was working with ghost explorer to remove some files from this backup. At one moment it stopped to work, I closed the task from task manager. Since that moment I can't access this backup with ghost explorer. With opening the backup with ghost explorer I get a message "Please, select the file for the last segment in this image file". I tryed every file of this gho backup, but nothing worked. I am still in this message and can't continue. There is an important information I need to restore. Please, provide me a solution asap. If there is no solution, that why do we need this software?

thank you in advance.
