There is a rare issue that the developers are aware of and are working on.
On some systems, when the Insert Lyric window is open, the Stanzas column and the Insert button my be missing.
We have discovered something in the registry is a bit off and deleting the specific key will allow MediaShout to create a new one. The zip file attached to the bottom of this article contains a new Reg Key. Once extracted, make sure MediaShout is closed and double click this file. There may be 3 or 4 windows that you will see. Please give the positive response (Run, Yes and OK) and the Reg Key will be replaced and resolve the issue.
