FWIW, I wouldn't sweat it too much, since in my opinion, Wikipedia is better viewed in the native browser, especially in reader mode. The app has no pinch to zoom, and while the browser's reader mode doesn't have zoom either, the print is larger in reader mode than the app is and is easier to read. Also, in the app, you can't copy text or pics, while you can in the browser. Plus, overall, the browser is smoother than the app.
Thanks I tried that and still the same error. Looks like I can't install any app and all give me the same error. This must be caused by upgrading to the latest os as I never had this problem before.
I would hate to security wipe it as that means losing data for the games and reload whole bunch of bars.
Really try to like my Playbook but there is always something makes me frustrated.
