If the Cascade50 connector is not syncing, it is worth checking the status of the connector application.
There are 3 simple steps:
Go on to the machine where the connector is installed and open the "Services" application.
Find the "Cascade Uploader Service" in the "Services" application and check to see if it is "Running".
If the uploader is not running, right click on the "Cascade Uploader Service" and press "Start"
