help -- need support from vbseo staff

i had sent a PM to the vbseo staff because i didn't want to publicly post my support request, but did not receive a response -- here is my question:

when i first purchased vbseo, i told the staff that i wanted to install the extension on two locations -- my test environment and my live environment. now i am doing upgrades, and i have already upgraded my test environment without a problem. before i tried upgrading the live environment, though, i wanted to double check to make sure that it was okay to do so, and that it would not be perceived as a piracy violation? meaning, i am registered to be able to upgrade at both my test and live locations, yes?

thanks for your time and consideration -- your attention to this matter is greatly appreciated.
