I've been using ACID Pro with no problems for some time, but today for some reason none of my projects play. They seem to open and load properly, but when I hit play, it's just unresponsive. The cursor stays put and nothing happens. The program doesn't "freeze", as I can move the location-cursor around manually and open new projects, etc.. all with the same result.
I've run no updates, done nothing with the computer, no new installs of any sort... absolutely nothing has changed since I used it without any issues last night.
