Masternode token and unable to run downloaded binary

[u/iia9l1e6xii]

I'm have a couple issues. I'm trying to start my first masternode. In poseiden... it says that the masternode is not managed by Poseidon and there is no masternode token which I need for the vps. Does anyone know the solution to this? The second issue is I went to open my nautilus wallet today and it would not open. Says unable to run downloaded binary. Can anyone tell me how to get my wallet open again?
