Redmine

I arrived at work this morning to find Redmine was not working. I've spent all morning trying to get it running and it doesn't work.
I'm using Redmine 2.2.
I've tried setting up the Windows service again.
I've created the service "Redmine", in regedit, I've added the Application key and have this set to

C:\Ruby193\bin\ruby.exe

I've created the AppParameters key and have this set to

C:\Ruby193\apps\redmine\script\rails server -e production

I then run the service and am unable to connect when I enter the URL in my browser.
If I run this from the command line

C:\Ruby193\bin\ruby.exe C:\Ruby193\apps\redmine\script\rails server -e production

I get the error
