I just came back and read this thread and initially I was going to jump in and maybe say something but it's cool, you sound like a good guy so lets just chalk it up to typical internet forum misunderstandings.
I now have my own problem. I just tried to run Real Band to check your point about generating a midi part on top of an existing Real Track (I would have never thought of that one) and discovered my Ultra Pak hard drive won't work. I haven't used it for a while, been very busy. It runs, I can hear it spinning but it won't light up and my desktop system won't see it, my laptop won't see it and I even ran Easy Recovery Pro and it won't see it either. I didn't copy it to one of my other externals when I first got it like all good noob's should thinking I'll get to it later so how stupid is that? Oh yeah to add insult to injury, for years now I also had everything on my C drive all the downloads, all the beta's and everything else but a couple months ago I deleted it all because with all the new stuff I was running out of space on my C drive, the external hd was running fine, so now I can't run squat. Dead in the water. I distinctly remember thinking you're going to regret this, I haven't backed up the Ultra Pak yet but my system was really running slow and I discovered I only had like 4 gigs free space left and that's barely enough to run Windows. I had over 40 gigs of various beta's and RT's on my C drive, I was jammed up I had to complete a project so I deleted that stuff.
I contacted support, we'll figure something out. Some expert, eh? Man o man o man. How many times have we all said to each other to make backups immediately?
I'm a tax accountant in my day job and every year I have to put stuff off during the first quarter and when tax season is finally over and I can come up for air, I do all the housecleaning both literally and with my computers. I had it all planned to do the updates like the new RT pushes and holds I downloaded but haven't installed yet, copy the hard drive and all that kind of stuff. Oh well.
