I'm having a couple of issues with Snapshot which I was

I'm having a couple of issues with Snapshot which I was hoping I could have assistance with.

The first is that when I click "run now" my backup for some reason is not running.

The second is that when I set the backup on a schedule, it will not execute.

The third issue is that when I try running the backup manually and having it send the archive to backup, for some reason Dropbox is detected but it will not send the file.

Any assistance is greatly appreciated.
