Earlier versions of LINKPlanner do not support the same prediction models. You must set the prediction model to a valid setting if you want to save in earlier versions of LINKPlanner.
The performance predictions will be different, so you should upgrade to 5.4.0 at the earliest opportunity to take advantage of the latest features and fixes.
Thanks,
