Error 500 usually means a server connection error. Can be just too many people downloading / server busy try a bit later or if you have it over wifi rather than over the Mobile network. The latest versions are available for Blackberry they are just not signed by blackberry (Un Signed) so you have to 'allow' unsigned/un official application install for this one application.
If that doesn't work,. Remove the battery and put it back in to force a full cold start reset for the phone.
You can't get Kik messenger on any Blackberry at all. The product doesn't support it so no way to fix it, sorry.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
