I have a Spanish program that requires Director Player 4.0 and I get the following error messages when I try to run it:"MCI Driver is not responding correctly. Try to reinstall the MCI sound driver or call Tech Support for assistance." After I click OK, I get this error message: "Unable to play. Error #1 MCI Error: MMSYSTEM263. This is not a registered MCI Device. How do I fix this error? Thanks in advance for any advice you can offer me.
