I just reinstalled MMM 2013 Premium and went through the process of clicking "Add", selecting the Soundpool directory, then clicking OK. Everything imported just fine.
It was late, I was tired, so I shut everything down and went to bed. Tonight I had a few minutes and was going to play around a bit with the app but when it loaded, no soundpools! Well, that's not strictly true, there were a couple.
All my Soundpools (some 60 GB worth) are stored on a local HDD. Because of space limitations on my primary SSD, I installed MMM on the same drive with the Soundpools. Other than being unable to "embed" the files within the app, everything else works perfectly.
