Run light turns off

I purchased a jamlink a year ago and have been using it ~weekly since then. Recently, when I plug in the power, the run light turns on, initially colored red. About half a second later the run light color changes to green, and then after another half a second the run light flashes orange and then goes blank. Even after the run light goes blank, the link light remains green with the ethernet cable plugged in. Regardless, I am not able to launch the jamlink control window online; it just shows "jamLink not detected." (1) Why is this happening? and (2) Why won't jamLink return any of my messages asking about this?
