NEW TO THIS, i have windows XP have the service pac 2, i have cable modem but i go thru aol, but SOMETIMES i use ie, i downloaded ie7 a while back and everything was fine, but i downloaded google earth and now my ie will not open, says the following add on was running when this problem occured, add on name companion.dll. i have tried everything i know. i can do things if i have step by step instructions, should i just uninstall ie7 and re install it, and how do i do that?? it causes some WEB pages to not load. thanks for all the HELP. glad i found this place. There are quite a few things that error message.
In IE7 try turning off ActiveX controls and re-boot the machine a few times.
Then re-enable ActiveX and see if the problem is gone.

Also do you happen to have a Creative Labs card in that machine ? ?
If so re-install the drivers for it.don't know if i have a creative lab or not, i cannot get into ie 7 to change anything, soon as the screen comes up it sends up the it has to close thing. any other suggestions?? thanks
