I downloaded it, opened it, a notification comes up saying "Could not start application." I click OK, but the Aces High File Downloader runs fine (or at least I think it does). There's a checkbox for the skin folder, I click it, and click download. It seems to download a P51D file (it downloads to fast for me to read all), then nothing happens.
I turned it off and turned it on again, same thing. Message pops up, click OK, click folder, click download, P51D file downloads again.
