Synch Not Working

When using Export -> Project to SD Card the error is returned: Can Not create Drum set folder. then the only option is to abort.

In Manager: There is new folder with several songs. all songs are saved with existing drum sets. All songs work in the manager. The project has been saved.

Also, If items are selected through the manager, the file tree shows where the item is located but when searching the computer file tree, all the folders show “empty”.

Does anyone know what the issue is?
