using 2.1.0 with Serato DJ on MBP. It had worked flawlessly. I used it a couple weeks ago with Serato SL, it also worked flawlessly but when I brought it back to SDJ now I have no video in the 3 ME preview windows ONLY WHILE using SDJ. It still operates properly with SSL. It seems like a setting or possibly a driver issue but I have looked and tested and not resolved it. Anyone have a similar issue or suggestion??
