Problem Importing Impulse Responses for Space Designer in Logic Pro 11. Dealing With .SDIR & .pst Files.

I just had some impulse responses from the Bricasti and Lexicon reverb units shared with me. Each of the two folders contained emulations as .pst files. The instructions provided were to drop the folders into the following finder path: Users/(Your Name)/Audio Music Apps/Plug-In Settings/Space Designer.

After doing so, I booted up Logic Pro and pulled up an instance of Space Designer. It recognized the folders, as they appeared with all of the proper sub categories and patches. When I went to select one, Space Designer prompted me to locate the file manually in Finder. The problem is that once I located the patch, I noticed that it along with all of the other patches (which are .pst files) are greyed out. I did some digging and found that the the stock apple Space Designer patches are all .SDIR files. I tried renaming the .pst file to .SDIR and loading up a patch (which I had a feeling wasn't going to work) and was met with (OSStatus error-108.). I also dropped the acquired folders into the Impulse Response folder found by using the following Finder path: /Library/Audio/Impulse Responses/Apple/. That didn't help anything either.

Not really sure what to do from here. I saw people mentioning that one would also have to have the .wav files in their possession in order for this to work properly (which I can request if needed) but I wouldn't know where to place those files in order for them to all work together for Space Designer.

Any ideas?

Thanks!
