There is problem with Cool Edit Pro v2 and cool_faac-1.28-2.7.zip from rarewares (probably). When an aac has been encoded with aacGain that Cool Edit pro gives an errors for the gain after which no aac audio is loaded. Likely many audio files could be now encoded this way (the mp3 idiots have found aac)
I have fixed the problem by placing flac.flt into coolpro2 with admin rights.
When placed with user rights appear strange work of CoolEdit under Win7 or Win.8, no matter.
When CoolEdit is opened by user everything OK and flac works.
When CoolEdit is opened by admin flac file is not detected, no matter Win.7 or Win.8
Such a strange tricks of Windows. When flac is placed by admin rights, everything works OK no matter how you open CoolEdit.
