Yes, one or more of your U.I. 1.1 downloads is incomplete. Right click the first part, Open With WinRAR, and click the "Test" button on the toolbar. You'll get a complete list of all errors in the entire 8 part archive. This will help you identify which part or parts are corrupt so you can download them again.

That is the only solution...download again.
