Are you using a Mac? Often importing projects with the "copy into workspace" checkbox checked will result in files being placed with the Mac "locked" file permission bit set.
Please find the bcbstmmaappwlMmaIphone-Info.plist
file in Finder, right-click -> Get Info. See if the "Locked" checkbox is checked. If so, uncheck it and see if you encounter the same problem.
You may have to do this with multiple files.
