You need to change the config and put a full route there:
Like:
::work folder
set "w_folder=NSCB_temp" -> set "w_folder=your route to NSCB_temp"
::output folder
set "fold_output=NSCB_output" -> set "w_folder=your route to NSCB_output"
If that doesn't work fine, Raidrive has an option to mount HDDs from a NAS i don't know if it fits your case but in case it does it may be worth to look into.

The free edition seem to work fine. If neither of those work i'll give it a check, though i can't give ETAs currently, since i have several things i'm working on right now.
