Cant open my files with MYOB

I encountered an error when I was working with MYOB. I was trying to access some accounting files, but I cannot open them. I was also trying to back up save my files, but I get the same error from M-Powered Services Support which I inserted below. I checked files for error, but I get the same error message. Now I couldn’t do anything. Please tell me how to fix this. Thank you very much.
