hmm...
i don't quite understand what's going on there but from memory it probably has to do with sessions previously saved on an old version of synthv1 and now you're trying to load them with a newer version of it... it's (probably) about dwelling the low and high note keyboard range being reset to none (which was the case on the older versions of synthv1 that did not featured the piano keyboard) please check it out....
hint: when that happens please hover either of the edges of the keyboard and click+drag to widen it up... and then save the session.
hth.
cheers
