ok, you have run nant recreateDatabase. It seems you have not run nant resetDatabase yet. I
You should find the user in pgAdmin in table s_user.
The other message about missing 'CurrentDatabaseVersion' in table s_system_defaults also is an indicator for the missing data in the database.
I just checked, the resetDatabase is included in the instructions at (http://sourceforge.net/apps/mediawiki/openpetraorg/index.php?title=Setup_of_Development_environment#initial_steps)
I hope it will work now!
When you get the latest version from git, make sure you run nant compilePetraTools patchDatabase compilePetra because we changed a couple of things. Then your server and client should display version 0.2.5, not anymore 0.0.9.
Edit: I just realised that at the bottom at your Server.log you have already version 0.2.5.
