LA Sound cdx-7405 CD changer HELP!!!!!!

ok here is the problem I seem to encounter.
I have win ME and am trying to install the LA Sound CDX-7405. Now it seems to detect fine initally but once anything is inserted into the tray the system does not recognize it or it lags the system. I am wondering if it is becuase I got bad drivers since they came from the windows CD and I never recieved a floppy. The problem is I can not find drivers for it anywhere. If any assistance can be given please let me know.
