IE7b2 won't work

[T D]

When I open IE7b2, it works for about 5 seconds before Doctor Watson (debugger) opens. I uninstalled it but now I can't use IE6!

No posts for Firefox and IEtab cos Ietab is really slow and for me, problematic.

I can't use 3rd party IE engine browsers like Maxthon either.

Help plz!
