I am very new to the application but picking up rather quickly...I have been reading through the posts and have found that I am having the same issues. I did download the NW viewer, then replaced it with the NW Viewer test. The test version printed one of my scores and all of the staffs. However, when I opened and printed the second one, it did not print the last staff line. You stated in your post: "A new version is attached. It now comes with the complete installer." I could not find an attachment. I am willing to try anything to get this to work. It could be my printer??? Don't know...HP C5240 All-In-One...may be the culprit. I am still trying different things to see if it will work.
