Ok I had this problem with the PMS not running error and this is what I did and got it to work. Plug your phone into your computer and push USB on your screen. Then go to The Quick Install and go to Tools and Device Management. Uninstall package manager service, Preware and then restart your phone and connect again but this time select "Just Charge" and do the same thing, go to Tools and Device Management and see if Preware and PMS are there too, if so, uninstall them as well. Then go install Package manager service first, then restart your phone, select just charge again and put preware on it and then it should work.

I was using WEB OS Quick Install 3.02
