It clearly says that Blizzard Support can help you better
This report will have state of your game, so they will more easy find the root of the proglem
Can you start the game without XPAM client at all? Will it crash too?
If so, how successful was your Warcraft 3 installation/patching process? Maybe there were some errors
Did you reinstall the game completely? I mean, have you tried also deleting old warcraft3 folder (after uninstalling it may still exist) along with same folder in your documents? (probably in my documents/my games/warcraft3 or my documents/warcraft III or something; i don`t remember)
