With those 100 points you can get Sonic Forest, Sonic Ocean, Interplanetary, Tetralogy, Kazakh Dombra or Furia Staccato Strings. Or 5% off your next order.
Signature Piano is great, but if you want something that doesn't require Kontakt try Soundpaint pianos.
Soundpaint is free (it works with Cakewalk or standalone) and they have a free piano and others that cost $40-$50.

It doesn't show as installed for me either. Clicking the library and selecting "Repair" seems to fix it. It still redownloads about 90 MB but at least it's not the whole library.
Another cool library.
They've released so many libraries that it's getting difficult to find what you're looking for. I hope they change the UI at some point so that you can find a library based on its name quickly.
We're currently at 44 to 28 free products. Luckily the last days have been better and at this rate we're very close to reaching 3000. Hopefully it speeds up at the end though.
