CEU14 - Vector lines not showing through a raster

Question

We are having issues with CE whereby vector lines are not showing through a raster. If the file is opened in v8i then they do. Note that the rasters are set to the background. 
 Why is this different and how do I make the vector lines show through the raster when using CE? 
 This is the view in Connect. 
 This the view in v8i, with the lines showing through.

Adding on with all of the great suggestions you should look at the following settings in relation to Display Priority, Update Sequence etc.
