Thirding this - I'm having similar issues with grabbing metadata, and it doesn't seem to matter how many titles I select at once. I did initially select my entire PS2 collection and fire off a metadata update, and that hung while downloading file 94 out of 10,000+, but then I restarted Launchbox, selected a single game and tried it again. It downloaded the metadata, the images appeared on the game, but it's been sitting at "File 14 of 14" in the download progress bar ever since.
To be clear, "hang" just means the progress bar stops progressing, the rest of the app still seems to work. However, if I try to click the red X on the download bar, it does nothing for a few seconds, then produces a spinning mouse cursor, almost as if the app's message pump isn't processing. Weird business - never had anything like this before in LB. Running latest, 13.18, also tried 13.19 with the same behavior.
