My Tartarus V2 worked fine until 3 days ago. On reboot it works fine until I see the device load in Synapse 4. Once I see the device loads the keymaps just fail. This seems to correlate to when Synapse was updated.
Initially Windows 11 refused to load rzpnk.sys. I disabled the driver checking and no longer get that error. But the issue remained.
I have tried to reinstall multiple times. I tried to get version 3, however that seems to be impossible now. (I tried an old version of synapse installer that was in my downloads folder from a year ago, and it still installed the latest version.)
I used device cleanup to remove all of the device references. At this point I am left with the most likely cause being Synapse 4 is not compatible with the tartarus V2. PROVE ME WRONG!
