I have several mobi files i downloaded from my pc to the kindle app but only 2 of them will appear when i open the kindle app. Itis alwaya the same 2. I tryed uninstalling and reinstalling the app from market but still the same result. I am on cyan 7.3 on viewsonic gtab. These same files open fine on my pc kindle app and my kindle. Any help would be appreciated. I am fairly new to android.
