Cheat engine problem

Hey i got a strange problem with cheat engine.. everytime i try to load up a firefox/ie window it pop out an error msg telling
"Error while opening this process"

any fix to this?

Have you closed all other processes of CE? If there is another one open, then it won't work.

Try restarting Windows, that sometimes does the trick. If all fails, uninstall and reinstall CE (if 5.5 doesn't work, try 5.4).

nothing of this worked as i tried already..

Can you try it with Chrome? (locking it to the specific page process?) Or Opera?
