I am session 11 of Português Level 3 and tonight when I opened Fluenz to being my lesson, a "user agreement box" appeared for the first time ever (it never did this all the way through levels 1 and 2). When I click on "I agree", it starts the program but then freezes up before the lessons box appears. The entire computer freezes up and I end up rebooting it to unlock it. I tried opening 3 times and it did the same thing. So then I tried opening Level 2 (which I finished back in November) and it did the same thing. The "user agreement box" came up, which it never had before, and then the program froze up. The other programs on my computer appear to be working fine. Any suggestions?
