Cubase 8 pro trial

Hey all, I entered the activation code into my trial version but every time I run cubase 8 It asks me to activate the trial period and Is only giving me 15 hours of trial? I updated my eLC to the latest version but still no luck. I try to enter the code again but It comes back with ‘This code has already been used and can’t be used twice’. Anyone got any ideas?

Cheers.
