I am sure Jack can explain this better than I can, but as I understand, ATX 2013 has two components. It actually installs a server on your computer, and the second component is the actual program itself. I am guessing this was done in an attempt to solve last years problems with workstations and a server. In reading the other board, it is a wide spread problem, made worse by 13.3. I am still working smoothly on 13.2, but understand that 13.3 will be required for e-filing sometime next week.
