"My Profile" in IE (Tools|Options) crashes browser (WXP-Pro)

[rexnervous]

And I can't find the reg key to try and delete what happened. Basically, I've never used this before, so I opened it up (Tools|Options > Content Tab > My Profile button). There was no entry at all, so I decided to start one. First time through no email address came up (even tho' default email was set apparently) so I redid it, adding a new email and deleting the default.

Ever since then, whenever I go to (Tools|Options > Content Tab > My Profile button) my browser crashes after I hit the button.

I could care less about this utility, long story why I need to test it out, however I do need to get functionality back. Anyone have any idea how to fix this?
