@smc
the error message indicates a problem with the mic input. in vent setup, is the input set for 'use directsound' and the name of the mic device?

does the mic work here:
Windows Vista/Windows 7
Programs / Accessories / Sound Recorder / create a recording then save it
Windows Media Player (WMP) / playback recording
