Just upgraded to 2016

Hi all

My Laptop hard drive failed failed so I replaced it with a super sweet new Solid State / clean Win 7 install.  WOW - well happy, my old laptops certainly got a new lease of life, but I took the opportunity to upgrade my SW install to SW16.  Not quite so happy with that.  The assembly I was working on, no crashes at all in SW15, now this afternoon two already.  The last problem wasn't a crash, it was fixed by close/reopen but my entire feature tree disappeared!

I am still on SP0.1 - we are entitled to get upto SP3 when we came off subscription.

I am wondering if the upgrade is worth the trouble.  My options are reinstall SW15 SP5 or SW16 SP3.

Either way I will have to pay for the service pack media, seems wrong to me that I can't download bug fixes as I am off subscription.

Legally am I entitled to obtain the service packs through a third party?  ...and if so is that something someone here could help me with?
