[SaF] no sounds playing

[Algis]

hello everybody, 
it seems to me that after deleting an old DOS directory on my hard 
drive, my computer ceased playing cd, mid and wav. in the last two 
cases it gives a message respectively, "mmsystem002 A device ID 
has been used that is out of range for your system" and 
"mmsystem326 No wave device that can play files in 
the current format is installed". Reinstalling my sound card 
software, Maestro driver for PCI-soundcard, gives no result. 
thanks in advance.
