Folder settings revert to defaults

Is there a way to stop Directory Opus from reverting to default settings every time I open it?

For example, I change the settings so file extensions were NOT displayed, and when I use Directory Opus again everything has changed and the file extensions are back. The same thing happens when I remove the attributes column. It is incredibly frustrating.

I am using the 60 day trial at the moment and thought that may have something to do with it, but not saving settings seems like a good way to put people off, rather than hoping they will buy the software.

See the Folder Formats FAQ.
