hello everybody, v tried the "tic-tac-toe" example of the multipoint sdk sample which worked just fine..but wen v tried to execute another code with most of the tic-tac-toe 's code v got an excetion saying "TypeInitializationException" ,v tried to throw the exception using try-catch,but all went in vain..dont know how to overcome it..also it says "microsoft.multipoint.multipoinSDK.dll.config not found "..here is our code...v are helpless..could any one go through the code and tell us where v went wrng?
