Razer Deathadder Chroma can't access settings through Synapse

Hi guys, I have a Razer Deathadder Chroma which I bought around 2015. It is considered a Legacy Device by Synapse and I need to download Synapse 2.0 to access it. Now that I have installes Synapse 2.0, it won't get me past the menu where you get 3 options saying: 1. Register your Razer product warranty 2. Visit Razer Store 3. View compatible devices I already filled my serial code in and it is registered on my account, but I still can't get a menu to change the DPI of my mouse. What can I do in order to access the settings of my 'Legacy' mouse?
