Unable to access my music files

When trying to access scores created in version 4.1.1.232071203 Revision :e4d1ddf I receive the following message:

The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again.

Which items? I need more information!
