animation shop layer help

[Reanimated]

I hope theres an answer to this, otherwise I wouldve wasted quite a long time :( . Ive created my character in Paint Shop Pro 7 using layers such as Head, front arm, back arm, chest etc.... Reason for this was because I was hoping that it would be easier to animated. Almost like 3D animations with bomes, where you can select a "joint" and rotate it, giving you more control. All went fine, and the character design is now finished (not coloured). However, I import it into Animation Shop, with all the layers merged onto one frame (thats the only option I could use otherwise each layer would be on a different frame. Problem is, now I dont know how to access the different layers that I had created, so animating now is the same as animating if the whole image was created as one layer. Hope thats not too confusing :o . Any suggestions on what I could do? Thanks
PS: Dont suggest photoshop :p
