Peter - unfortunately (for you ) I don't have a 64bit OS simply because I'm waiting on the "smoke to clear" so to speak.

I have posted your question on the cakewalk forum and I will post the replies here.

I have a suggestion for you, tho. I suggest you contact cakewalk about bundling TTS-1 with BIAB. As you've already mentioned in another thread, you can download MC5 for $40 and get TTS-1 that way - maybe you and cake can come up with a bundle for much less than that.
