As said before, the .shared file is not re-created at distribution, but created when the document is first opened by a user and populated when users add bookmarks or objects in the document as clients to the server. So, if you don't have any backup of the .shared file you deleted, the content of that .shared file must be considered lost. The .shared file is a persistent storage location, not a temporary entity, and must be backed up just like thje .qvw file it belongs to.
However, if your .qvw file is corrupt, not much might be possible to do. It's rarely we see .qvw going corrupted, so (again, as said before) try opening the .qvw in a local developer. If that does not work, consider restoring a backup.
It is quite strange if the file is getting corrupted every time when you are distribting the report . In this case you can contact the qliktech guys directly. They can provide you the exact solution or if this is some kind of bug then they will response accordingly.
I think it's a Bug ..
try to restart the services
delete all shared file/logs files get generated in that folder
rename the application
open application reload it and save it.
see if lucky then enjoy ur day
