Under certain situations it is possible that the synchronization service can crash, and the software may not be able to restart as the service is still running and cannot accept calls to close from the software or user,

Detailed below is a procedure that will manually kill the service
  1. Click the Start menu button
  2. In the search bar type 'Run' then press Enter on your keyboard
  3. In the 'Open' bar type 'services.msc' then press Enter on your keyboard
  4. Look for YOUR Sellerdeck Synchronization service
  5. Once you have found your Sellerdeck Synchronization service, right click on it and select 'Properties'
  6. Identify its 'Service name' then make a note of this for later.
  7. Select 'OK'
  8. Close the 'Services' window.
  9. Click the Start menu button
  10. In the search bar type 'CMD' then right click on the CMD program that appears in the list and select 'Run as Administrator'
  11. In this black window type: -
    Code:
    sc queryex "servicename"
    Replace '[servicename]' with the name you made a note of earlier.
  12. Identify the 'PID' for your Synchronization service and make a note of this.
  13. In the same command prompt now type:-
    Code:
    taskkill /pid [pid number] /f
    Replace '[pid number]' with the number you make a note in the previous step.
  14. Press Enter on your keyboard


Both commands should look something like this:

Code:
sc queryex "SellerDeckSyncServerV18"
Code:
taskkill /pid 2712 /f
