WordPress MU

I installed wordpress mu and can see the blog, but when using IE I am UNABLE to get into admin section. I click the link for site admin (mysite.com/wp-admin/) but it hangs for awhile and then I get the message: internet explorer can not display the web page.

This is odd because I just installed it 2 hours earlier and i was able to get into admin. but i had to delete that install of it because I had chosen "sub domains" but my host (lunarpages) said they dont allow shared host to use wild cards. so i deleted the wordpree mu and the mysql database and redid the install. now IE can not view the admin page. BUT if i use firefox, i can get into the admin page. what is the deal with that?

* No, i did not enter "www" on install
* and it just worked on prior install, but now wont work.

the htaccess file has all of this in it.
