Tartarus Pro Synapse Problems

Hi, I've just received my new Tartarus Pro and now spent hours on trying to get it to show up in Synapse.

The Tartarus works, but just as a normal keyboard, but will not show up in Synapse.



I have tried removing the drivers, reinstalled Synapse 3.0 several times, removed Razer related keys in registry and so on, but nothing seems to make it show up in Synapse. I do get Windows message saying that the Tartarus Pro have been successfully installed.



Does anyone know how to fix this, so that the Tartarus will show up in Synapse 3?



Thank you in advance.
