Synapse 3 won't launch on boot

All of a sudden, Synapse 3 won't launch automatically anymore when booting my new system of approximately 4 weeks old. What I tried so far:

• Multiple clean installs
• Deleting registry entries
• Setting all Razer services' startup type to 'Automatic (Delayed Start)'

However, nothing seems to help. Can anybody help me? Having to start some piece of software manually each time you turn on your pc, only to provide basic functionality like a keyboard, is very annoying.
