Move license to another pc permanently

I have to move the license to another computer because the other one is not working and I can not uninstall it. Now I have the proof of a new machine but I do not like the activation because still active on the other. 
I sent an email to activation@draftsight.com to request the release so that I can activate the trial version I have on my new one with my credentials.
I can not call because I could not communicate in English. Can someone help me? thanks Maura
