Want to reuse a license I bought, but not sure how

[timekiller]

I previously bought a license, but stopped using it for a while. Now I have built a new server but don't have the usb drive I used, and can't find a way to re-use my license. Can someone help, or will I be forced to buy a new license?

Contact support with the email you used to purchase the license.

 

Or, if you keep old emails, look back through them, the info should be there.
