I was inside LaunchBox yesterday, and i was editing game info, to check mark some games into "completed" status, when suddenly there was a power outage and the pc shut down abruptly. When it finished rebooting and i was welcomed with the message root element is missing and some other sentences and i cannot go into launchbox. Probable something was being written into the launchbox configuration at the time the pc shut down and it now got corrupted. Read some posts about deleteing system.xml
Where may i find it, and if this does not solve the problem what else can i do. It would be lengthy to reset launchbox and start from a clean slate
