Synapse 3 doesn't detect BlackWidow Chroma V2 and Mamba Elite after two updates

Hello,

since the last update (I guess it was about two weeks ago), my Synapse 3 stopped detecting my keyboard BlackWidow Chroma v2 and my mouse Mamba Elite. Everything was working fine and I had no issue with it until I updated the app.

Today it updated again to version 3.4.215 and I thought that would solve the problem, but it didn't.

I tried to do everything listed at the forums and reddit, like unplugging the devices, restarting, restore the application, uninstalling, uninstall and update drivers from device manager, etc... But nothing worked for me. I have Windows 7 Home Premium, but I don't think that's the problem because two updates ago everything worked fine.

I don't know how to fix this and I'm really annoyed for not having my lights in sync /: (?)

Thanks in advance!
