First open the pindle bot ini located in the bots folder make sure your pass is listed correctly...
Second make sure your on the right realm
Third
you may you gotten hacked....or the bot somehow managed to change your password...in either case the best thing you can do is call NOT email call blizzard IMEDIATELY and tell the that your pass no longer works and if your talking to the right person they'll ask for your cd key
give it to them
its been done before just dont mention pindle bot tell them you downloaded a loader utility so you could play without the cd
hopefully you have access to a good virus scan program like nortons to check your system for any remote administration tools(thats how they get your password)or it will just happen again and get rid of that program you thought was pindle bot
