I edit in two different locations and on two different systems. One system is v6 and the other is v6.0.5. Will I have any issues opening up saved files from v6 on the v6.0.5 set up?
That should not be a problem.
frankly, there's no good reason to NOT update the system running 6.0 to 6.0.5
the 6.0.5 update fixes bugs in 6.0, and is presumably the final update for CS6
