Probably a dumb question but I just wanna ask anyway. So when I opened the launcher it downloaded (assume it was the update) but when I launched the game it closed and the security on my computer said homecoming.exe was a high risk and I needed to reset my computer immediately. I deleted the whole file I had that everything to do with the game in it. What exactly should I do? Reinstall or was there something simple I could have done to resolve this issue? Thanks in advanced!
