Battery 3 not in Native Access, Offline Activation is gone. Are my projects done for?

Hello. I have performed a re-installation of an operating system since pretty much 5 years ago and now I can't get my old projects back.

* Battery 3 is 32 bit only. JBridge is refusing to convert it to 64 Bit.
* I can't even install / activate my old Battery 3 from Komplete 7 anymore.
* Native Access does not list the plugin and I can't just but battery 4 because all my songs I need to open were not written with battery 4 so it's useless to upgrade.
* Old legacy license activator does not even run because NI have killed the servers and the offline activation shows this.

Any other avenues I can take?

 

You can download the installation files from this page:

I didn't install the program but imported all the kits into Battery 4.
