Unless the unit has been officially transferred to the maker space I don't know if you will be able to download Vcarve or not? Most any software that will produce G code will work but Vcarve is far and away the best. Maybe (and I'm not staff so I can't promise), but maybe with the SN, you can get the unit transferred.
As to the SB software, I am guessing that the board will need to be flashed to work with the latest version. There is a utility buried in there, I think under help that will start a card update.
Your best bet is to call during the day. The SB staff are SUPER helpful.
