I click toolkit update on the interface, maybe once every 2 months, i tried to do the latest update about a week ago and i got the hardcore, POTENTIALLY UNWANTED PROGRAM with the red X.. never happened to me before until this last update. I assume the latest updates dont do much so I'll play it safe and use the tk i got, any thing about this for you?

Download Rocksmith Toolkit link worked. I did get the warning when i clicked update on interface, could be a personal firewall issue. 2.7 through link worked.
