    my e260 says "error occured trying to obtain device certificate." when i try and sync rhapsody files to it. time and date, usb mode are all correct.



1 Answer

Here is the message I was getting; "Windows Media Player cannot synchronize or burn the protected file because the Player cannot verify that the license is valid. A problem occured while contacting the Internet to determine the current date and time." I looked at my device, Sansa e260, and the time was off by 1 hr. and 10 min. I corrected the time on the device and it worked fine after that......

Certificate error on web site.

This is basically an Internet Explorer 7 Website’s Security Certificate problem! You have to self-sign the certificate on the client computer or add the URL manually to the trusted security zone. When you are trying to access a secure web page, you receive the warning message:

"There is a problem with this website's security certificate. The security certificate presented by this website was not issued by a trusted certificate authority."


"Security certificate problems may indicate an attempt to fool you or intercept data you send to the server."

To fix this issue, you can follow either of the methods:


Method 1:

You have to install the Microsoft Windows Small Business Server 2003 (Windows SBS) self-signed certificate on the client computer. To do this, follow these steps:

  • In Windows Internet Explorer 7, click Continue to this website (not recommended).
A red Address Bar and a certificate warning appear.
  • Click Certificate Error button to open the information window.
  • Click View Certificates > click Install Certificate.
  • Click Yes, to install the certificate, when warning message appear.

Note: For Windows Vista users, right click on Internet Explorer icon. Select Run as Administrator.

Back to top

Method 2:

Add the URL to the Trusted Sites security zone:

  • Open Internet Explorer
  • Go to Menu bar > Tools > Internet Options.

  • Click Security > Trusted sites > Sites

  • Type the URL in the Add this website to the zone text box > uncheck Require server verification >Add > click OK

  • Click OK to exit.


Now you have added the URL successfully into the Trusted Sites security zone.

'Problem obtaining the devices certificate'

the songs on the player have expired licenses - you have to renew your music service sub and try reloading them

Make sure you are connected to the internet, and make sure that your music service subscription is up to date. If both of these conditions hold, and you still get the message, then delete the songs off the player, and reload them after converting them to Mp3 format - the WMA format is the only one that has a device certificate problem.

This error can occurs because the VeriSign Certificate Authority (CA) has changed the hashing algorithm that is used for new Secure Sockets Layer (SSL) server certificates from Message Digest 5 (MD-5) to Secure Hash Algorithm 1 (SHA1). A supported fix is now available from Microsoft for Windows CE 2.11 and Pocket Explorer 3.0 this fix can be found at: Note: After you have downloaded and installed the fix, be sure to soft reset the device.
