I am using Pro Series for 5 years and today was the first time this happened. Nothing has been changed on my computer.  I have to click few times to resolve issue and than it works.  Really annoying to have 4-5 times popping error massage before system e-files. I will try to shut down and restart hope this will give permanent solution.  

Thank you all for sharing your experiences. Saved me so much time by not calling customer service.
