Material Section Hatching

[907Trekker]

Hello,

Is anybody having trouble hatching material sections in their section views with anything other then a solid hatch in Civil 3D 2011, SP1? 

For example, in the attached image I have a material "ex for filter mat" that is currently hatched with C3D's standard SubBase hatch which is basically a solid greenish hatch.  If I change the style to any other solid hatch, it works.  If I change it to any hatch like in the image "AR-Conc" (I'm using C3D's supplied style) the border will appear but the hatch will not be there.  I also found that if I open any drawing I did in 2010 all of my hatches do not appear. 

I have tried changing the hatch scale, drawing scale, check all layers were on / thawed, made different styles, made sure the style in the "compute materials" matched the one under "section view group properties".

I'm at a loss, am I missing something obvious?

Thanks,

Mark
