I know this is an old thread, purchased the MU-2 a couple of weeks back when it was on sale. Getting the following "x-aviation error fetching url http://www.x-aviation.com/merchant/wrapper.php". Tried all of the things listed: re-downloaded file, ran as administrator, nothing working. Help!!
No problems with skymaxx pro 3.0 or urbanmaxx.
