I have DraftSight V1R4 installed on an XP computer. It was acticated some months back and then computer was disconnected from internet. Now suddenly I got request to re-activate. I tried after again enabling internet on this. But even though I put all the fields and tried with various email accounts, I never received any activation mail.

I tried to install 2015 version but seems this is not suitable for XP. I uninstalled that and have again installed V1R4. Now I am getting "Activation server" error and have to click "Activate Later". DS opens  for now but not sure what will happen after 30 days. How to solve this issue.
