A few days back I successfully installed Vegas 18 pro, without any further actions.

Today I was rearranging the windows layout of the virgin Vegas 18 to my own preference (undocking, docking actions).

No media installed, nothing other than rearranging, then Vegas suddenly hung forever, you know: the wheel turning, not responding... I even went on a long break to see if it was recovering, but no. Report send to Magix.
