Just got off phone with SCT and they loaded a beta software on the server for me. I guess it will automatically update when plugged on but it will also say there is new software available which apparently you DO NOT want because that will put it back to the released version and not the beta...
I got the same issue with my X4. Was in contact with SCT last Friday 4/17 and all they pretty much blew me off and told me I needed to update. IT IS UP TO DATE!!!!! Been talking to a few other people on the 08-10 6.4 Facebook page with the same issue. Hopefully find a solution soon
