So Ive been furiously reinstalling all my machines to Windows 7 RTM (one of the perks of being in a Windows feature team :) ).
Today one of my machines had a nasty issue with Zune after I had my PC count reset (I have three machines I wanted to run RTM on so I had to get my three PC limit reset to allow all of them to register properly). Basically I tried to download content and it told me something was wrong with the licenses and threw out a nifty (read:cryptic) error code.
It seemed my DRM registration was a bit bad. Zune does give you a link to reset your DRM setup, however that only works with Vista and XP. Heres how to do it manually:
1. Stop Zune and WMP2. Delete all the files underneath the Windows Media DRM folder. In Windows 7 and Vista this is located at: C:\ProgramData\Microsoft\Windows\DRM3. Visit this link and “upgrade” your DRM security http://go.microsoft.com/FWLink?LinkID=345064. Restart Zune
It should fix it. Let me know if it works for you!
Do you know if there is a way to reset the count on the Microsoft servers? I have a few bought files (non-mp3) that don't let me download them anymore because they limited number of time/machines. I only have the Zune software on 3, but I have reinstalled a few times and tried out the Win7 Beta and RC.
You can actually call Zune support, lik I did, ask them to reset your PC count. As you know, you can only add or remove one PC in 30 days. If you reinstall all your machines like I did, when I installed W7 RTM, then you run into issues with this count. Explain the situation to Zune support and they will clear the PC count which allows you to re-register your 3 PC's that you want Zune on.
