just did the up date and must of been using 32 but updated so now how both. I have a few songs using a audio track that hasn't worked for awhile must of been 32bit. but open biab in 64bit and they work.

That's good you updated. I don't think your problem is related to BIAB, except that perhaps the program in 32-bit is looking in another place for your audio file? Technically there isn't any reason you can't do the same thing in either 32 or 64-bit versions. The audio track is neither 32 nor 64; it's probably 16 bit, the CD standard.

thanks for the infor. glad to have those songs back
