Context menu customizations not saving

Running on my own machine, under a poweruser account. Every preference setting I change (including filetype and context menu modification) sticks. So, I decided to dive into customizing the context menus, following the tutorials on this site, reading the forums, reading the manual/help/userguide/et al. I'm fairly sure that I know what I'm doing. That being said, the following two customizations will not save no matter what I do...

  1. I searched through the registry to find the correct GUID and successfully added the WinRAR context menu to the "All Files and Folders" filetype. I also tried to reorganize this menu somewhat (put WinRAR above cut/copy/paste, start a new group with cut/copy/paste, delete the "create shortcut" item). However, when I exit all of the dialog boxes, the changes never stick. WinRAR appears between Cut and Copy, no matter what I do. Also, the "create shortcut" item keeps coming back no matter how many times I delete it.

  2. I don't like or use the folder tabs feature, so I edited the context menu for "All Folders" and deleted the "Open in New Folder Tab" option. Once again, when I exit the dialog boxes the option to Open in New Folder Tab is right back where I tried to delete it from.

I've tried this under both shared and private configuration files and it's a no-go. I've tried restarting DOpus, logging out and back in, and restarting the computer, and nothing fixes it.

Soooooooooo...

I had the same problem but after reinstall, all are ok...
