Information for people (like me) who purchased Pianoteq from another user:
I was disappointed today to see that I did not receive the upgrade to version 8, even though I bought Pianoteq less than a year ago. I figured out, however, that I probably wasn't eligible for the upgrade because I purchased Pianoteq from another user, who had purchased it more than a year ago. So I upgraded for the special price of $29, which really isn't a significant outlay for a major upgrade.
After I installed version 8, I saw that I was also supposed to download the upgraded Studio Edition, which DID include the new Classical Guitar package. I had upgraded to Studio on my own, directly from Pianoteq, so I guess that meant I was eligible to have a complimentary upgraded Studio even though I had to pay for version 8.
I was very happy about this, and thought I'd share the information.
