You do NOT want to hit "Send"--that report goes to Bliz, and you don't want them to find evidence of bot-hooking tied to your account from the crash remnants.
Instead, look in your <WoW_install_dir>/Errors/ folder, and see if you can dig out one or more files that represented your crashed WoW, and attach it here.
You're looking for a *.dmp file and a corresponding *.txt file with the same base name. If they're too big, just Zip them.
