New build keeps reverting to 'demo version'

Aaarrgh!! So, this has happened several times tonight: I'm cruising along working on a filter. I go to save it. FF decides forgets that it's the pro version and tells me that the demo version cannot save, and that I should upgrade to the pro version. (I have the pro version, of course.)

I've lost several hours of work today because of this. It does NOT seem to generate an error report.

I already treat FF very gingerly, creating scores of intermediate files for data safety, backing them up and never, ever, editing a filter via photoshop.

But this... this is not acceptable.

We've released the fix. To apply it, download the installer from our Download page and install it over your current version. Please let us know if the problem still persists.
