I can't get SNAP 2016 to work in Canvas. I've downloaded the program. I tried cutting off my firewall just to try that. I've also tried allowing Flash to work for everything. In Canvas it just keeps asking for my code. I know my code is good because I contact SNAP customer service on chat twice and they told me it is good. I've contacted my Professor several times and no one else is having this problem. What am I doing wrong?
