In a multi-tracked VIP file, everything was working fine, recording, playback, all working as they are supposed to work. Then suddenly the playback function stopped working. When I hit the spacebar the cursor jumps ahead slightly and then stops but no playback happens even in that small space. If I hit "Home" the cursor returns to the 0 position but the same thing happens when I hit the spacebar and it happens from any place that I move the cursor to There are no ranges. I restarted the program, same problem; then I restarted program, loaded another file, same result.

Samplitude Music Studio 2013 Free Trial version, Windows 7 Professional, plenty of storage space, plenty of memory. only Internet Explorer running in addition to this program.

Coincidentally, however I don't remember in what order this occurred, I was trying to purchase the program and had difficulty there as well, and I ultimately gave up trying. It is possible that this malfunction occurred after that but I'm not sure about that.
