I did everything fine, I only have Local and FX checked, using only 600~ megs on my 8 gigs of ram, i have plenty of space but keep getting a "NodeSpecCache - Unable to open NodeSpecCache for writing." Error. When I run retail it works fine, when I run unleashed using those parts of the thing, locak and FX only, using 600 of my 8 gigs of ram it gives me this error. Is there a solution?
