Windows 7: EMET 4.0 blocking everything after reinstall, why?

EMET 4.0 blocking everything after reinstall, why?


I have used EMET 4.0 many times. This time however it seems to be blocking Firefox and anything else that trys to access the net. it says something like "simexecoverflow", i think...

the only thing i had done different is uninstall Zonealarm free firewall. Can't really think of anything else. Anyway, EMET 4.0 wont really work now and it has in the past, perfectly.

Any idea what I can do?

Are there leftover EMET 4.0 files I should remove and try a clean install? Where are they?

Thanks for any help..

Looks as if the 4.0 version of EMET came out in June.
Did you have it installed, or version 3.5?

What programs do you add to EMET?
I have installed EMET and imported the two lists (I skipped the certificate list). I have added Sumatra PDF, but nothing else yet. I'm not sure what other programs I might want to add, or if anyone has had issues when adding certain programs to EMET. I can see the logic behind having Java, Adobe...
