Unless I am misunderstanding, I think you have two choices:
1) If you upgrade to Vx1.1, you will have the new import functionality
2) If you have to use Vx0, you can export the netlist from Eagle, and then import it into DxD
I've only used Eagle a few times, but I think you can download it and use it for free as a trial, at least long enough to get your netlist
Also, there is a friendly and helpful Eagle User group forum where you can get help. They were very responsive when I had questions
best wishes,
