Trying to create a photo project (PCD) in M PSE 10 (Win 8.1x 64) - have finished putting putting together pictures and effects but am having trouble adding music. The problem is an error message about certain songs, which I know to be restriction free, that says: "We cannot open this file because your system does not have the correct compresser/decompresser(codec) installed."
It seems the files in question are MPEG-1, level 3 files. Can anyone help me here. I don't know which way to go.
