problem with bsplayer, ffdshow and ac3filter

i really need some help

while trying to test out some features with dvd's on zoomplayer i updated my ffdshow files and somehow have lost the ability to run audio through the ac3filter.

i'm outputting all ac3 content directly via spdif to my receiver for decoding, but i used to be able to utilize ac3 filter for everything else. now i don't show it as a filter in bsplayer or as a drop-down in the filter section of audio configuration in ffdshow.

i've done all the obivous, reinstalled both ac3filter, ffdshow and bsplayer, i've set ac3 filter to preferred etc...i'm really puzzled here, can somebody please help me. bsplayer is using the fraunehoffer codec for mp3 playback, i want to send it to ac3filter. please help.
