CorelDraw X3 cracked / broken disc 1

I have a major problem and wondered if anyone could help. 

I have X3, but the first disc has a crack from the centre out and will no longer load. Is there anyone in the community that can help. 

I have my serial number and the other discs are fine.

I did contact Corel support and they pointed me in this direction.

Recent unemployment means a newer version is not on the cards and help with this would allow me to start using my old vinyl cutter

in the hopes of starting a little craft venture.

Regards
