Well, I tried the full and the incremental updates, and Vue will not render to disk with either one. Imports objects fine, though. Funny, it will ask me if I want to overwrite the file ( I had, in a previous version rendered a test ). Frankly, it seems to me, that E-on must test their software on a couple of computers, then let her rip. As for the BAK folder, this time I just copied the contents of the Vue directory to a new folder. C'mon, e-on, jive us a break!
