You are allowed to use the same license on multiple machines that you own, so that shouldn't be a problem.
It shouldn't be possible to damage ones license either. Maybe there was a database connectivity issue, so you could try again and see if it works now. If not then please send an email to support@pyxeledit.com with details and I'll fix it for you.
BTW, the lag is not fixed in the 0.3.108 you get from the download buttons, but in the prerelease available below on the page.
