Ok so first you must download the 3.0 EDU which gives you export_descr unit along with 3 other files. The export_descr goes in the mp edu backup folder, the other 3 go in your EB/data folder. Then, after you have done this, download the EDU hotfix. This contains two files. The export_descr again goes in the mp edu backup and replaces the other one while the other file goes in the data folder. Hopefully this helps.
