Hello, I always used the timer crack. Before I wanted to install sp1 I updated my BIOS from Asus A8N-SLI motherboard with the SLIC table as described in the tutorials by flashing it with a modified bios. Also activated the Asus certificate and the Asus Ultimate key, my system looked as if the timer crack was still in control, nothing changed and my system still wasn't activated. As I have read in the forums that sp1 will remove the timer crack I started installing sp1. After succesfully installing sp1 on my system, it now says 15 days left for activation. So at this moment I tried again to activate the certificate and the ultimate key. But still nothing happens. Please can someone give me advice how to activate? Thanks in advance!!!
