Hello friends, I have cubase 6.5 and Snow Leopard 10.6.8. I’m about to buy the upgrade to pro padshop bank transfer. It turns out that looking at the Steinberg web version of this padshop pro trials to 10.7 (Lion) (?) No padshop pro to 10.6.8!?!?!?!
Hello, I just made the purchase, and all is well here. 
I had issues with my bank letting the purchase go thru though. They had to disable fraud protection for the day lol.
At the end I will not buy any steps did not the bank or anything. the purchase is canceled automatically?
or I will send an email threatening to kill me and my family?
Say what?!? 
Aloha k, DO NOT KILL PEOPLE!
