I'm having the same problem with Aeon Platinum, and sent you a support request last night (ticket 66654). I've also been a customer since 2006, and I trust you will get this solved.
I intended to re-up G-Force and/or WhiteCap soon but I think I will wait until the license server is working.
My Aeon Platinum continues to say "You did not enter a valid license code. Please check that you entered it correctly". Are you still trying to solve this? Can you maybe invalidate my key that I paid for last night and just give me a new one? I have no idea if that would work; I'm just getting frustrated that I still can't use the software.
I'm sorry, I didn't realize your time zone. I did try it just now, but I don't expect you to work on it right now. Please enjoy the Sabbath and weekend, and I'll try again next week. Thank you!
