Solution 1 – Reset the SugarSync Manager

While data conflicts between SugarSync servers and your computer is one of the major causes of syncing issues, it was singled out as a possible cause of the app quitting unexpectedly.

1. Open the SugarSync Manager application.
2. Press and hold the CTRL + SHIFT + R keys on your computer’s keyboard to initiate the reset procedure.
3. When the reset confirmation dialogue box pops up, click ‘Yes’. SugarSync will reset itself and shut down.
4. Open the SugarSync Manager app again and enter your login credentials in the respective fields. Ensure the box asking whether you want to restore the sync folders is ticked, although it should be checked by default. This will enable SugarSync to synchronize the data between its online folders and your computer.

Solution 2 – Uninstall and Reinstall the desktop app

If the application keeps on crashing or quitting unexpectedly, there is no much you can do beyond uninstalling and reinstalling the app. After uninstalling the app, be sure to download and install the latest version.

Later versions come with bug fixes and also addresses issues with the previous versions. If the desktop app continues to misbehave even after a reinstall, then the issue might be with your account.

Also keep in mind that any file name with more than 255 characters (file path included) will cause syncing problems.
