i put the second agatha christie in and it plays but will not recognized it,
By "the second Agatha Christie" do you mean CD 2 (the second CD) of one of the Agatha Christie games not being recognized after a disc swap?
Or are you talking about any CD from Agatha Christie: Murder on the Orient Express" (which was the 2nd Agatha Christie game made by AWE games) not being recognized?
Or are you talking about a casual game series?
Also, are other CD's reading properly?
If there is a problem with more than this one CD, check ***this thread***
at Microsoft forums for a fix.
If this is the only CD that gives a problem, then it's a problem with the CD, and might be related to the DRM that was used.
