Q: Converting Data from Songs on Logic Express 6.4 to Logic Express 8

Hi Musiciansfriends,

I have a lot of songs on my old harddisks I recorded on Logic Express 6.4. I lost the XS Key to that. I then bought a Logic express 8.0.2 some years ago witch runs well but does not open my old data. Is there way to convert these datas, maybe a programm in between the two versions that helps to brigde the gap?

Thanks for help! Markus
