To downgrade you must select again an old hardware. When you own it, you don't use GGCoins.
So you can try to downgrade the spare 36W and after you get a new Power Supply, and after you upgrade again.
In some minutes i will add the default pass to the database, so you can connect to the users that don't choose a password for the system.
I get your suggestions and i will introduce this new things in the 1.3
- Missions where to earn GGCoins (in fact if you look at userlist, you see the IP of some Super Servers)
- Create TXT file
- New missions and commands
EDIT : Ok database + server side updated with the default password "nopass"!!
