I have TT installed on two systems and am working on the same return on both. If I update one system, and do not copy the tax data file over to the other one, the second system will not activate (gives error) when TT is started.
Once I copy the updated data file over to the second system, TT runs fine on it. Not sure if this is a bug, or an absence of instructions on how to run TT on multiple systems with the same data file...
