You don't specify but have you updated LE to v.9.1.7?
Sometimes Logic can be a little picky as to how you open the song file, so if one method doesn't work, try another. For example:
1) Drag the GB file onto the LE icon.
2) Right-click on the GB file and choose "open with Logic Express."
3) Select the GB file from Logic's Browser tab in the Media window on the right.
I'm assuming that you already tried File>Open from the LE menu bar.
Once you do manage to open your GB file inside LE you will be required to save it as a Logic file.
