okies ... good. which means that your cd-rom is having problems
reading the 2nd cd. a few methods to get around this ...
1. buy new cd-rom drive (hehehe)
2. insert the cd, let it run until it can be read. then the error
message saying that cannot detect cd should have a RETRY button.
click on RETRY.
well, no guarantee that this would work. but, it's your best
bet.
