Generally when we run into this type of issue, the underlying issue is that Windows Media Player is unable to successfully write a DRM cookie to the local DRM folder. Please follow the steps as shown. If anything looks different than described in the guide, please take note of it and send an email to
support@cbtnuggets.comStep 1: Please be sure you are using Windows Media Player 11. This is included by default on Windows Vista and Windows 7. For Windows XP Service Pack 2 or greater see here: Windows Media Player 11
Step 2: Verify that ActiveX trusts the www.cbtnuggets.com domain
1) In IE; click the "Tools" menu, then click "Internet Options..."
2) Click the "Security" tab
3) Click the "Trusted Sites" icon
4) Click the "Sites..." button
5) Type "www.cbtnuggets.com" into the text box labeled "Add this Web site to the zone:"
6) Click the "Add" button
7) Clear the checkbox for "Requiring server verification (https:) for all sites in this zone"
8) Click the "OK" button
9) Make sure the security level for the "Trusted Sites" zone is set at "Medium" or below by moving the slider to "Medium" or "Low."
10) Click the "OK" button.
Once this is completed, please try to play one of your nuggets. If your nugget does not play, please see the next step.
Step 3: Verify that the user account is The Local Administrator on the workstation in question. Please do not use a domain administrator account, nor an account that is simply a member of the local Administrators group. We rely on a set of registry keys specific to this account. The Local Administrator user must be used for this process.
Step 4: Rename the DRM folder.
1.) Unhide the DRM folder
a. Click Start, and then click My Computer.
b. On the Tools menu, click Folder Options, and then click the View tab.
c. Check the "Show hidden files and folders" check box.
d. Uncheck the "Hide protected operating system files" check box.
2.) Locate the DRM folder. Depending on your OS, the DRM folder is located:
- Windows Vista/7: C:\ProgramData\Microsoft\Windows\DRM
- Microsoft Windows XP and 2000: C:\Documents and Settings\All Users\DRM
- Windows 98: C:\Windows\All Users\DRM
- Windows Millennium Edition: C:\Windows\DRM
If you still do not see a DRM folder after doing this, please open a command prompt and run the following commands:
a) cd "C:\Documents and Settings\All Users" (or to the location of your DRM folder as specified above, enclosed in quote marks)
b) dir /a
You should now see DRM listed as a directory. If not, the folder does not exist and you can safely skip to step 4. If the folder does exist, run the following commands:
a) attrib -s -h DRM
b) ren DRM DRM_Backup
3.) After finding the Folder, please rename it to DRM_Backup. If you receive a permissions error, first verify that you are performing this as a local administrator, then reboot into safe mode and try again. Instructions on booting into safe mode may be found here: http://support.microsoft.com/kb/315222
4.) Once the folder is renamed, please navigate to http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp?force=1 in Internet Explorer and attempt to apply the DRM CRL update located on this page. Windows Media Player will want to do a Security Update. Allow the update to complete - it should take less then 2 minutes. If this update fails, please verify that you are logged in as The Local Administrator account, then take a screenshot and include it in your response.
Step 5: Disable all antivirus and firewall products such as ZoneAlarm, McAffee Firewall, Norton Internet Security, AVS, Panda, Trend Micro AV, etc.
Step 6: Verify that there are no viruses infecting the workstation in question.
