Picturenaut conversion seems to be working for the short run. I hope this will be fixed very soon because this, relying on some other software to convert HDRI in order to have the exact same results as we had two releases of the same software before is, to mildly put, unacceptable.

Submitting bug report now that I have some time as well.

Note: having to reenter my license key even as a registered user every time a new issue is submitted is annoying as eff.
