He intentado abrir algunos archivos y me sale este error, antes no se
generaba pero ahora no me deja. ¿Que puedo hacer?

Hola

Mira a ver si te sirve esto:

1. Update the device driver for the sound card or for the sound
controller. To determine whether an updated driver is available, visit the
Web site of the component manufacturer or visit the Microsoft Update Web
site, http://update.microsoft.com .
2. Use Device Manager to determine the status of the sound card or of
the sound controller. Follow these steps: a. For Microsoft Windows XP,
click Start, click Run, type devmgmt.msc , and then click OK.

For Windows Vista, click Start , type devmgmt.msc in the Start
Search box, and then press ENTER.
If you are prompted for an administrator password or
confirmation, type the password or click Continue.
b. Expand Sound, video and game controllers, and then locate
the name of the sound card or the sound controller.
c. If your sound device is listed but a red "X" appears next to
the device, the device is disabled. To enable the device, right-click the
icon, and then click Enable.

If the sound device does not appear in the list of sound
devices, expand Other devices. If Multimedia Audio Controller appears in the
list, right-click the icon, and then click Update Driver or Update Driver
Software. Follow the instructions that appear on the screen to locate and
install the driver.
If you cannot locate or install the correct driver, contact the
computer manufacturer or the manufacturer of the sound device for more help.
3. If you do not have a sound device installed in the computer,
install a sound card, and then try to play the file again. For information
about how to install a sound card, contact the computer manufacturer or the
manufacturer of the sound card.
4. If you are trying to play a file over the Internet, the server
might be temporarily unavailable or there might be a network issue. If this
is the case, try again later.
5. To resolve the problem, make a copy of the file, and then edit the
ID3 header in the original file.
Note The ID3 header is the part of the file that stores album
information, such as the song name, the artist name, the album name, and the
genre. This information is also known as the "tag." You can use a
non-Microsoft ID3 tag-editing program to remove or to reset the file's ID3
headers. You can search for and download many ID3 tag-editing programs on
the Internet. After you remove the ID3 headers, the Zune software should be
able to play the MP3 file.
Important When you try to remove ID3 headers, you can damage the file.
If this occurs, the file may become unplayable. Therefore, always make a
copy of the file before you edit the header.
6. If these steps do not resolve the problem, the file itself may be
corrupted. Download the file again. If you still experience this issue,
contact Zune Customer Support.
