I always use Chrome for my browser, but I need to use IE for a specific thing, and I have to enable a website so it won't be blocked on there & I have to go to Tools-Internet Options, but for some reason, everytime I select it, it won't work.

I also tried through the Control Panel & that won't work either. I also tried selecting Security from Control Panel, but that isn't working either.

I even tried to go and uninstall Internet Explorer, so I could reinstall it. However, it's not listed in the Uninstall programs...

I really need to get this working, but I have no clue how to do so, because I've never had this problem before..

Update:
Disregard. No longer need help with this.

Excellent! Glad you figured this out on your own. IE can be a nuisance sometimes.
Did you consider the IE-compatible plugins for Firefox or Chrome? Ir outright use an IE clone browser instead of IE? Worth looking into!
