I have a licensed version for SU 2014 which is valid through 10/2015. I ran through the SU website dialogs to get a new license for SU 2015 64-bit. I inserted the license, which the SU website indicated was valid for SU 2015 and it continues to keep me in TRIAL mode.
It appears they have fixed the problem internally. I’ve just reinserted the license info and it has registered properly. I cut and pasted into the “Advanced” window. I did email the issue to SU earlier today, so I don’t know if it was an account issue or something else.- at any rate, it has been resolved on my end.
We did have an issue this morning, but sorted it out… yours might be in that bucket. Specifically, if you had any characters in your name or company name it would cause our servers to create a corrupt license. Most typically this was the inclusion of an ampersand (&) but could have been a few other characters.
In any case, that’s all sorted. Sadly our fancy new error messages didn’t capture that properly. )c:
