I have been using SAGE without issue for the past year. All of a sudden yesterday I couldn't open SAGE. I received a troubleshooter message that said that my computer firewall is blocking required processes to access my data. Then is gives me a whole list of processes that I need to add to my firewall's list of permitted programs.
I entered them all (painstakingly) into my firewall list and it's still not working. I haven't changed my computer or computer protection software or even my ISP. I don't understand how all of a sudden (at tax time), it doesn't work. Help!
