GarageBand Download

Hello

The latest GB 10 update (June 30th) stopped downloading half way through and would not continue even when prompted to.

Now, the download bar is greyed out and I cannot close the window.

GB is fully functional but the window (download) remains open.

This is annoying to say the least, on top of the incomplete download, i have to deal with a constantly open window that all I can do with is Minimize it.

Help please?
