Saving With Phx Objects

When I save a game where I’ve used objects from the Phoenix final pack, it doesn’t save correctly. When I load it, all of the phx objects are welded in place and can’t be unwelded. Not only that, but built-in objects can pass through the phx objects, but only after a load. Is there any fix for this? I’m almost positive I installed it correctly. I’m running Windows 7 64-bit if that helps.
