I am trying to install "Cell Tracker" on my BB 9780. I have downloaded the software to PC, used Winzip to unzip the files, connected to cell phone using USB cable. Everything moves over to the phone. I open BTExplorer, set permissions and downloads OK but when I try to "run" the app i get the error message "Uncaught Exception: Java.Lang.NoclassDeffound Error” or “error 907 invalid jar”. What is the problem here. Have tried uninstalling and reinstalling numerous times and keep getting the same messages.
