I've looked through previous posts, and I could find some that were similar to my situation, but I couldn't find any that where the exact same.

I had a non-DNN site that I needed to convert to a DNN site, lets call the site "websitedomain.com"  I needed to transfer the "websitedomain.com" domain to godaddy (my hosting site) just to keep everything together under the same host for convience.  While this transfer was pending, I created a new domain at "websitedomain.info" and created the new DNN site at that temporary location.  Once I got the ".com" domain on godaddy, I just switched the hosting plan from the ".info" site to the ".com" site.

And this worked, sort of.  Typing in the "websitedomain.com" domain brings up the DNN site I created, but it puts up the "websitedomain.info" in as the address.  The ".info" site no longer has any kind of hosting account associated with it.  (I had a feeling this was going to happen when I created the .info site, but I had to get the DNN site created ASAP as time was of the essence.) 

I need to know how to get it so that when typing in "websitedomain.com", it displays the site with the "websitedomain.com" in the address bar, which is the correct address of the site.

Thanks in advance!

I forgot to mention I tried that already.

It won't let me delete the alias of "websitedomain.com/installation directory"

I tried adding a new alias of "websitedomain.com", but it didn't work. 

Also - I had to move the hosting back to the "websitedomain.info" domain and just point the "websitedomain.com" domain to the .info domain last night because it stopped working on the .com site.  It turns out godaddy was just having the one hosting account apply to both domains for a limited time in case things took a while to switch over.

I tried changing the alias while it was still being hosted at the .com domain.

Still don't solve the problem?
