Reactivating Draftsight on new PC when old PC has died

Hi

I am trying to active Draftsight on a new laptop because my old one died.  That means I can't access the serial number or deactivate Draftsight on my old laptop.  I have searched the internet but cannot find an answer.  I thought this situation would be common enough.  Any help would be appreciated.

 

Thanks.
