3000 isn't a whole lot to lose.
well. it wouldn't for me. Although I've been doing a LOT of C# lately about ~337K keys and over 16 thousand mouseclicks over the last few days!
All I could suggest, is to try using something like Total Uninstall or Revo Uninstaller to try to completely eliminate all traces of whatpulse, then try to reinstall.
Does it give an error message when you try to start it?
