Alright, I've tested your data and it's working fine, so it doesn't appear to be a data issue. Are you using LaunchBox inside of any kind of a syncing app like Dropbox, Google Drive, or OneDrive? Other than a permissions issue, I can think of two possibilities: either some sort of app conflict, or perhaps a file system/corruption issue. Or it could be a disk space issue even.
So I would first check to make sure you have plenty of disk space, and then run chkdsk on the drive to make sure that nothing is awry. Then try closing all background apps to see if it makes any difference.
