Ok, so here's my problem: About a week ago, I decided to upgrade Internet Explorer 6 to Internet Explorer 7. However, my mom decided that she didn't want IE7 and had me roll it back. However, we had the Yahoo toolbar, but it disappeared after I rolled it back. I think the toolbar thinks we have IE7, so it's running on the IE7 version. I tried reinstalling it, but it didn't work. How can I fix this?
