Bamboo - Internal Server Error when re-setting up local build agent

I am still in the learning phase here. I installed bamboo on a local machine and was running it manually as root. I recently re-performed the setup, intended to run as 'bamboo' instead of root. I now also have it running as a service, and I added "plymouthbuild" to my /etc/hosts so that I don't have to refer to myself by an IP address.

When the service was up and running I accessed the main page (http://plymouthbuild:8085) and I was prompted to enter my license key. I re-entered the same key that I used when I did this the first time. (I bought one of those $10 keys).

The page changed and said "please wait while setting up bamboo..." or something like that. It never did finish. It just sat there showing me that spinny-graphic and saying "please wait".

I got bored and opened http://plymouthbuild:8085 again, only this time I was asked to setup the administrator account, so I did. When I submitted the form, bamboo crashed and showed me that page that you see below.

I do not find the logfile that is mentioned ("attach the atlassian-bamboo.log log file found in your application home"). My folder is empty:
