Connection to mainframe stopped showing files

Im using version 5.17 and connecting to a mainframe its been working just fine. Today when launching the application and connecting an error pops up. Error listing directory.....unexpected directory listing line....After i clear the error i see files in the remote location but not the ones i need to see.

I have attached a screenshot of the error. any help would be great . Thanks

How would you interpret the record? What is the "49"?
