hi guyz...i'm trying to back up my downloadable version of poser 7 as you all know its almost 2 gig in size...i'm using nero version 6 to try back up poser 7 on a dvd writable disk but it keeps spiting the disk back out...any ideas on how i can make poser7 any smaller in file size or get this thing backed up so i know its nice and safe on disk ?
