Everything seems to work fine, but when I re-open LaunchBox nothing is imported. Will it not use MAMEUIFX as the emulator?
*edit* Ok, I ran it again from the beginning and it worked this time. The only difference I could see is that I closed Lightspeed before I re-opened LB.
*edit* One initial problem that I notice is that if you ran Lightspeed more than once it creates duplicate emulator entries in LB that you have to clean up, even if you have rolled back to your backed up Launchbox.xml.
*edit* After importing, when I run a game, it says the rom file does not exist, even thought the file path is right.
