I sanyone else having this issue, and if so how did you fix it? I've re-installed my driver, and reinstalled serato, but as soon as I plug in my mixer, serato says it is connecting and may take a minute, but just stays frozen. If I click anywhere, windows offers to shut the program down. It doesn't matter how long I leave it, the software just stays frozen. This is a new issue, I can't remember if it is since the update to 4.0 or 4.01, but I'm running 4.01 now.
