I recently scanned all of my library (~63,000 tracks), which took a few hours. When I try to run de-dup it gets stuck at about 90% of the way through and makes no further progress (the 90% is just an estimate since there is no official percentage count). The files are all stored on my local hard drive. Do I just need more patience? After letting it sit for about 90 minutes without any further progress I assumed something must be going wrong.
