Here is the deal, my Sibelius 5 comes in tomorrow.  Right now I'm currently running VDL2.5 and SIB4.  My question is this: If I reformat my computer, as in completely erase everything, will I be able to install VDL2.5 again once i reinstall all the software on my computer?  I am not changing computers, just erasing everything from it.  I've let my computer become junked up with things I don't need, and decided to get a fresh start to make things a little smoother with Sibelius 5. 

Will this work?

Zach - since the system ID used by Native Instruments is based on specific hardware items in your computer, you should be fine in doing this. I would suggest starting with installing VDL 2.5 immediately after your reformat just to be sure. If you do encounter authorization problems, you'll need to notify NI and let them know that you've reformatted your machine which was already successfully authorized and they should be able to get you on your way. Most likely, you shouldn't encounter any problems.

Ok, great.  Thank you very much for the reply.

I've reformatted my main drive a few times lately (I keep my documents, samples, and stuff on another drive) as I tried Vista and went back to XP.  It's not a problem.  In the past I had to de-authorize my previous system at NI's website.  Recently I didn't have to since the service center update.

Ditto.

I haven't tried this since the update, but when I was having a bit of hard drive woes I ended up coping my files to a few different locations for use and backup. For each harddrive that I copied my files onto, NI saw it as a different computer and I had to reauthorize. Is this still the case with Partitions and backup drives?
