Need help with Ultima 7 exult

Hi.  I bought Ultima Collection for the PC years ago, and haven't been
able to get Ultimas 6-8 to work (including Serpent Isle).  I
downloaded the Exult program, but get this message when I try to open
the Exult file:





Exult Ultima7 Engine

Warning

Could not find the data files for either "The Black Gate" or "Serpent
Isle".  Please edit the configuration file and restart Exult.





Could someone please walk through this with me, by e-mail or chat?  My
different chat lines are:

AOL Instant Messenger: "RodPrime2316" or "HotRod2316"
Yahoo Messsenger: k904re29dan
MSN Messenger: [EMAIL PROTECTED] (e-mail, as well)

Thanks in advance!
