I've just set up a masternode on a VPS and I'm really not sure if it's running ok or not!

On http://explorer.tokugawacoin.com/masternode it shows as ENABLED but my active time is always 00:00.

I did receive one reward of 11.2 TOK  3 days ago but nothing since then.

Do I need to keep my wallet open on my PC to keep the masternode running?

My wallet is also locked every time I open it. Is that a problem? Is there a way to permanently unlock it?

Sorry about all the questions - I'm completely new to this!
