The profiles forget all settings

Something on your system is stopping dBpoweramp from writing to the registry.

I'm trying to create a profile that converts from flac to m4a and mp3 at the same time, with dynamic names. The conversion also works. But when I access the profile the next day, it has forgotten all the settings I created and starts as an empty profile. This worked on my old computer - but it no longer works at all on my new laptop. Please help.
I first create a profile, then I convert. It has been saved ever since. Or do I have to save the profile “after” the conversion to a profile name?
