Query: No In-depth User Manual

Acid Pro 4.0 has a lot of functionality and I have enjoyed using what little portions of it I can. However, I give the product 1 star because it does not come with an adequate user's manual. It has an extremely light weight 10 page "guide" that isn't worth the paper it's written on. There was a guide published but Sony has discontinued it, and I can't seem to find one. If you've already used the program, you'll be ok. Otherwise, stick with Acid, the non-pro version. Having all the functionality and not being able to harness it stinks. :(
