Shadow issues

I just downloaded the cammy mod and I don’t know why it doesn’t appear but I can see a shadow and I am new to gmod.
I am using gmod 11 and please help me

There is no GMod 11. Did you purchase it on Steam?

Post a screenshot

it’s gmod 10 sorry, and it gives me an error

Looking at the graphics settings you run on GMOD has probably fallen back to DX7. Meaning the shadow is disabled

my problem is why the cammy model doesn’t appear not the shadow thing and when try to load the cammy model it gives me an error like in picture above.
