Interested in buying Notion Software

I have just bought (but not tried) notion for iPad. I also wanted to buy Notion desktop but I have a little problem. I have an older computer that used to be my main workhorse, with Win 7 64 bit and it should run notion just fine. It's just not as powerful as my newer machine but it has a ton of RAM and what was a very fast processor in 2008.
However, I am going to soon buy a SSD for it, in order to speed up launch and operations in general and since the case is excellent, eventually I wanted to also upgrade the motherboard.
By my calculation, if I buy Notion today (and clearly IO'll want to use it ASAP) When I will buy the SSD and rebuild the system, I will use one license. When I upgrade the Mobo, there goes the second license.
Will I be able to reactivate a third time sometime in the next 3 months or so?
Thank you.
PS: I have a few orchestral VST plugins from my "Sonar 3" days. But they are 32 bits. Will I need to buy them again? I used to do a lot of music back in 2006 to 208, but the computer I was using was stolen and now all I have left are the backups of my purchases (and not all). Will some of them give me an eventual 64bit version or will I need to buy all new? We are talking Garritan and Miroslav Philharmonik. I haven't cracked those since the laptop was stolen
