Hi, 

So I have a fresh install of CC on a new machine. I have 1.5TB HD space on both drives. I set the custom content and template paths to my D drive on install, as this is where I store all data for all applications.
When I try to open one of the Smart Gallery packs I am told "The hard disk space for the Template is not enough. Please free up some space and try again"
There most certainly is enough HD space!

Any ideas anyone?
