Plaxo crashing Outlook Express 6

<font color="green"> I just re formated my computer and when I go and open my Outlook Express Plaxo locks up and I have to re start my computer there are times I have to re start it several times I like using Plaxo but this is getting annoying I even un istalled and re installed it. I am hoping that I will get a response whenever I have posted in the past I never got a response back </font>
