So I just updated my TI Nspire CX CAS OS to 4.3.0.702. I grabbed Ndless 4.2 from ndless.me. I have the installer, resources, and .cfg, but whenever I attempt to run the .tns installer, it crashes and reboots. Before I updated to 4.3.0.702, when I still had 3.6, along with Ndless 3.6, it worked great. Is there something missing? How should I go about solving the problem?
