Database Manager requires a full working PinballX or Touch Play installation.
You need to setup your own systems and all that you want within your front end.
Systems can be managed by Database Manager, but cannot be added!
Also Windows Media Player needs to be installed on your system
NOTE: For correct working of some features within DBM, you need to put FFMPEG.EXE (not included in the PinballX installation) into your PinballX root folder.
FFMPEG package, can be downloaded from http://www.ffmpeg.org/
