I have a Pandigital Planet running Android 2.2. It is working perfectly, except, I have "GO Launcher EX" installed. Apparently, something has damaged the launcher's code. So, when it goes to the home page, the launcher stops responding. How can I bypass the launcher to reinstall it, or how can I uninstall it so that the default launcher will run? I didn't knowingly change anything, nor have I installed any new apps or updates.
