After installing my Moraff Mahjongg software CD and trying to open the program, I get the message, "A required .DLL file, LEAD50N.DLL, was not found."

I deleted the software and just tried to download another mahjongg program and the same thing happened.

I haven't received this error message when trying to do anything else.

I have no idea how to correct this problem.

Any suggestions?

Thanks.
