Hello. I seem to have a recent problem with Vista on my new HP pavillion dv9000t laptop. Both Itunes and Windows Media Player will not play any media that is opened in those programs. When I play a song in Itunes, it acts like it is playing but it stays at the 00:00 Time frame and does not advance. In Windows Media Player I get the following error when trying to play a song: Windows Media Player encountered a problem while playing the file. For additional assistance, click Web Help. Web help tells me ERROR CODE C00D11B1 that my sound device may not be functioning correctly. However Websites that have music on them, play songs without any problems. I am also having this new wierd error with my networking connections. On the icon in the status bar, it tells me that Connection Status: unknown and that the Server execution failed. However, I have no problems with my wireless internet. I am also getting messeges from Windows telling me that I Have security problems. It is telling me that I do not have a firewall activated which i do (NORTON) and no malware problems. I can not do a system restore because I found out this computer did not have it activated automatically. These problems seemed to have started happening yesterday. Any help please?
