I have completely uninstalled MB3 from my system as of today. It is just painful. It freezes way too much and takes about 6 or 7 freezes and attempts and reboots even to create one simple session that actually works. I know I said it seemd to settle down before and it was working Ok for a while but not now. It does not like my RME sound card either. It is not RME's fault either. Everything else runs like a dream on my current system.
Be careful about buying this right now. I don't think they do refunds either so beware.
It is not ready and I mean not ready. They need to do some serious fixes on this before I would even consider it again.
I actually tried my 32 bit machine and tried to run MB2 inside that and it was also very unstable and just painful as well. I have removed that from that computer as well.
