To retain your old settings you may have to copy your old config file/s to a new directory. To find out where the new directory is on your computer, run the program and go to the Traces tab and look on the 14th line, the line that says "Profile directory:", that is the folder your config files should be saved now.
If you use the "media library / cache" option you should reset it.

Note: As this is a PC side application, you do not need a JailBroken PS3 to use it with your PlayStation 3 entertainment system.
Recent build changes include the following:
- Double check for Mplayer existence and font generation (useful for latest Sherpya's revisions)
- Ability to shutdown DLNAorgPN automatic support for a given renderer (see DLNAOrgPN attribute in the renderer conf file)
- Some hack stuff for mpeg2 remux on Bravia TVs
- RAW generation fixed
- Custom mencoder quality settings for a given renderer
Not sure what changed in 412 specifically though, all I can find is "small change" (suspect a bug fix).
