Is it possible use a Owned License twice?
 

Greetings, I bought a owned licence (125£) since some time, and I'd like to know if I could use it twice, one at http://clanheroes.es and again at http://inf3rnales.com

Both are my sites and I don't use them to get any money, they're free (blog like) sites. Am I allowed to add the vBulletin to InF3RNaLeS or that's illegal?

Thanks!
