Cannot open include file lg_defs.inc

[Franklin W. Cain]

It's been a very long time since I last tried to use POVRAY. I just now exported a model from LDView into POVRAY, but when I try to render this model in POVRAY, I get the error message "Parse Error: Cannot open include file lg_defs.inc". 

I've tried searching tis site (not just the Forums), and I've searched Google as well, but I cannot find anything that actually helps me fix this error. 

Please advise. 

Thanks, 
Franklin
