If you back up your songs to a CD-R and later restore them, you may have trouble using the song files.
This is because Windows makes all files written to a CD-R into "Read-Only" files. Once marked this way, the files cannot be edited - meaning our software cannot rewrite or modify or delete the files, such as to increment the usage information, or save changes you make to the lyrics.
The software will warn you when a a song is read-only, but you'll still need to know how to fix this problem.
Close the Worship LIVE! software.
Open your My Documents folder, and find your Worship Songs folder within it. (Or, of course, find wherever your songs are stored.)
Right click on the entire folder of songs, and select "Properties" from the popup menu.
Near the lower left corner is a checkbox marked "Read-only". Click this checkbox until it is clear - not grey ("mixed state") or checked. Then click OK.
You should now be able to use your songs as before.
