When I installed launchbox it just "knew" about all the games I had installed on my PC from steam, windows, etc. I installed a new game in steam and launchbox didn't know about it. So, I wanted to rescan my library. I deleted my "computers" section, but I can't figure out how to re-scan it. When I select "import steam", it wants me to configure api keys, and urls and stuff. I know i didn't do that stuff the first time. How do i go about re-importing my game list?
