Upgraded DCS Explorer to v1.2, but now it doesn't work. The red track power light no longer comes on and when I try to connect an engine the error message is it can't find a DCS Explorer. The Explorer is still on the MTH vs Home setting and the iPad is connected to the DCS network. Deleted and reinstalled the App. In LuCi it shows the new firmware was installed. Reflashed a second time, but no change. Each time I have waited at least 5 minutes to be sure the download completed. I tested the system before upgrading and it worked fine so something happened during upgrade. Also put in a new fuse just to be sure. Any suggestions?
