I have the same which happened randomly for the past week. It's so annoying that I called in the hotline in US and reported the case.
Guess what... the support staff said that he suspected there is something with my notebook and insist to do a remote session to check it. However, when the time I asked him to send me the link to do so, he told me that this is a paid service.
Come on... I am also an IT folks. I did try couple notebooks and mobile devices (through WiFi router / direct connect) that I verified that everything it's alright before I called in.
What kind of support that is? Seems I need to consider to move on another product with better real "SUPPORT"
