Existing files will not save after update.

[saltwater.nights]

After the most recent software update, I've opened files that I update on a regular basis and find that once I try to save them again, they won't save. It says there is an internal error. I have lost hours of work. I tried creating a new document and saving it, and it worked. What can I do?

We have a fixed an issue for this in our beta version. You can try it out here :-

I have the same problem. When can we expect the beta version out as a full release? Asking as we can't install betas on our work laptops.
