I've opened the file in MS 5EX and show you, how it should look in the new version (5.0.2). 

I've used so much layers, 'cause every color need an own layer. 

In the bottom-line of the layer window are two "new layer" buttons, one for a Vector layer (the default for drawing) and one for a Raster layer (to use with rastered materials). The attached letter A is a hint for text work. 

Go to menu > windows > material ... and you can get some materials. There are simple poses for drawing along and comic frames too.
