You'll have to pardon me if I'm incorrect on a few things here, so I'll work with what I can based on the information you have provided...
Would I be wrong in guessing that you had enterprise-x as your start page before you removed the module? If so, go to your admin panel and select a different module for your start page.
If you have other modules installed, you can choose what you want to appear on your start page by going into system admin>blocks. Once there, you can decide which blocks gets placed where. For instance, you can have a poll on the left side, your news block in the middle and so on.
Naturally, you will have to be logged in to make these changes. Also, after you decide on what blocks you want to have throughout your site, you will need to go into your system admin>groups and allow anonymous groups to see the content blocks you previously selected.
If any of this is confusing at first, thats ok. You'll get a feel for admin navigation through out your pages in no time. You can always hit us up here on the forums for your Q & A.
Good Luck
