I have outlook 2010 and whenever I try to open it , it automatically shuts down and an error pops up saying MS outlook has encountered a problem and needs to close answer in the error report content its written "AppName: Outlook.exe
AppVer: 14.0.4760.1000
AppVer: 14.0.4760.1000
ModName: Kernel32.dll
