If you have the new Version 2.0 it is listed under the applications tab. It does not have to be running to add to QL. If you are using an older version, it is not able to be added that I know of because it cannot be running and activate QL at the same time. When QL first came out, you were able to do this, but since, there have been a few upgrades.
If you have not downloaded the new Version 2.0 upgrade, I highly recommend that you do!
Open quickpull to the point it says are you sure you want to re-set you're device.
Launch QL - BB menu key - add item - scroll to the applications button and click that, quickpull will be listed as the app to add. Add it and save :-)
