The NavBar SoftBar issue was that they disapeared completely after a reboot and apps on sdcard!
I had a similar problem when my SD card was inserted. Back up your data from the SD, mount it directly on your PC using an adapter and format it on there. Insert it back in the TN7 and then try again, it solved the issue for me. I haven't had any softkey loading problems since.
Try clean the cache to see if that helps! As for the Nav and Soft bar issues its now fixed since 4.4.2-2.4. But even before that i did the Sdcard wipe and start again with the same issue coming back time and time again!
