Hi Oshyan. Apologies - inaccurate reference to 'database' on my part. Although all programs are installed on aC:\ drive, the working data files (about 60GB) are kept in separate folder on a D:\ Drive and this is the 'database' I was referring to. Had to share D: as a network drive, then map a logical path to it from the new PC (my render box) and from existing PC (where Blender, Xfrog and a couple other programs to create assets to use in Terragen ( which is installed on the Render box). In order for everything to work correctly both PCs need to see identical drive mappings to every asset. When troubleshooting the app crashes I finally moved my database to a 3rd PC on the network and the crashes seem to have abated. It's an easier setup to work with in that I can easily set up identical drive mappings from Render box and Asset creation box. It's a bit slower, but I'm not so quick myself anymore, so it's a workable solution.
