Error on activation?? Key not found on server? in Battlecruiser / Universal Combat (Legacy) Posted October 27, 2007 · Report reply Did you read the part where I said that it was protected with the UCSE signature? Guess my attention to detail isn't what it should be. Anyway, I found my original Box purchase of UC and got that installed and am playing that for my fix. I'll keep my eye out for the patch that removed the activation as you've stated. Thanks again for your help.
