Hello, I'd like to do the MOOC from Berklee. I have downloaded the V 220.127.116.11. It's written "Windows 7 SP1 32bit/64bit and above, OSX 10.6.8 and above on Intel Macs only." So It should work on my system, but I have a message "Strobe2 had expired". Is there a way to make it work on my system ?
