Sorry, Alan, I really don't have an experienced answer for you, but my instinct tells me to take it out of the press, break up the curd and get it salted.
I've had a couple of cheeses where the curd remained very soft and I pressed them for up to 12 hours, removed them from the press, re-salted if they tasted like they needed it, then put them back in the mold and pressed again. So far, they turned out good.
I hope someone with practical experience will chime in soon.
