How to run draftsight offline on ubuntu 12.04 LTS 64 bit

Dear all,

I am an architect, and my requirement is to work on field and off field as well. Is there any way that i can run draftsight without an internet connection. I had registered it a few days ago, and clicked on the internet link today (the gap between activation and confirmation by clicking on the link from my e mail would be 3-4 days) and suddenly when i try to use it offline it simply doesn't open.... any solutions??

 

Regards,

Rahul
