Address bar is gone, help!

[otter]

The address bar that should show up on the top of this page isn't there. Normally if I wanted to go here I'd type in www.twoplustwo.com , for example. Well I can't type anything in because that "space" is no longer there. What can I do?

I was deleting some registry files and may have got carried away at some point. Since I probably shouldn't have done that I can't tell you what I deleted, but it was probably mostly porn related [img]/images/graemlins/blush.gif[/img].... I also checked temporary internet files and deleted some things but that shouldn't affect anything right?

I checked the files that came w/ dell and I can't find an internet explorer file. Can I redownload IE someplace? Will that solve the problem?

Thanks in advance
