Playbook not funtioning since upload yesterday

My Playbook has been "glitchy" to say the very least since I have had it. (6 months) I uploaded the latest OS upgrade yesterday via wi-fi. After it was complete, I connected to my Desktop Software and uploaded what appears to be the original software/starting point as if it just came out of the box. The problem I am having is that once I connect to my home wi-fi, I proceed to the AGREEMENT screen but nothing appears in the drop down menu for Country.....HELP! I am getting to the point of gassing this if it is going to be this much trouble.
thanks.......

Did you restart your PlayBook after the upgrade? Sometimes this is necessary.

I did the restart......nothing. I am going to let the battery drain and try it again. Thanks for the advice...
