From my desktop. Opening up the .pdf files no longer works. And entering my login and password is of no use.

I purchased 8 tutorials in August 2019 and have been studying them. Now I go back to one of my tutorials and it says that my offline access has now expired. I put in my user name and password and it cannot find the eMastercam server. What gives? I need these tutorials very badly and I paid well over $600 for these. What do I do? These are on the same computer on which I purchased them and downloaded them. And I have been able to open them previous to today. HELP!!!!!

I am just now getting the opportunity to program a Mill/Turn machine. What is the best tutorial to get to learn how to program the multi-axis mill/turn? Regards,] arlen_one
