When the SSFE agent tries to synchronize, it just keeps on spinning without any notification about the progress.
To resolve the issue, rebuild the Windows client database:
- Log out your SafeSync Windows client.
- Delete all files under the folder %LOCALAPPDATA%\Trend Micro\OSDP.
- Delete $(sync_root)\.sync.cache.
- Log in your Safesync Windows client again.
The procedure above should rebuild the file status database and the client should properly run now.
