I have the same problem. Can you be more specific on how to reset the paths in the import window? The "manufactur" default seems to need the paths to ~/Pictures and ~/Movies no matter what. On mine, if I rename the /Pictures and /Movies symlinks (i.e. /Pictures1) in the Finder (OS X Mountain Lion), only then will Lightroom open the import dialog and will create its own /Pictures and /Movies - will I have to do this every time I want to import?? Thanks.

Where am I deleting what from? I just re-installed LR and it still won't import unless I change the names of the symlinks. Only then will the import dialogue open, in the absence of the /Pictures and /Movie folders. Then it creates new folders, in the Finder, and also in the import dialogue.

I'm renaming the symlinks on Macintosh HD. They replace the old /Pictures /Movies folders with the link that shows up where they normally do, and they're linked to the actual folders on my 2nd HD.

Secondary drive holds all media and files, due to the large size. The OS is on the primary drive, where I've replaced the folders on the primary HD with the symlinks, so media folders are redirected.

Again, the symlinks are in the exact same place as the folders would normally be. MacHD/Users/~/Pictures, etc. They replace the folders. They work like an Alias, or shortcut. In the Finder, and most other applications, these folders show up because the symlink redirects you to the folders on the 2nd drive.

Ideally, Lightroom would either open the import dialogue and show the symlinks, or not show anything at all and still open up. Apparently, there HAS to be folders with the names /Pictures /Movies in your User directory, otherwise Import refuses to open. That's my complaint I guess. Even if LR isn't being correctly redirected to the folders, Import should be able to open up according to what you say.
