I downloaded an fli from a forum today. Whenever I run it, whether through the Windows Media Player or directly from AAWIN, after about ten seconds I get a General Protection Fault in Module aaplay.dll. What do I do? I assumed that the dll was corrupt and downloaded aawin again, but no improvement. My system is a 486sx/33 with 8 Meg and no duplicate dll or drv files anywhere. I had been (and am) running with aaplay.dll and the mciaap.drv (if I recall its name correctly) in c:\windows\system, all other aa-related files in c:\windows.
