I am having a problem with a number of file types on my computer. I am using Windows XP and Service Pack 1. (I wasn't too thrilled with service pack 2 and because of the security involved, alot of things on my network failed to work properly, so I uninstalled it)
Specifically, MP3 files.
I am able to open mp3 files as long as everytime I want to open one I have to select a program from a list of programs. Windows tells me it "Windows cannot open this file" and lets me select from a list of programs. I MAKE SURE I check the always use this program to open this type of file and then the file opens. Problem is, no matter what I do, windows will not open that file automatically, even if I make sure Windows Media Player is my default player. I also went to folder options and noticed the file type MP3 does not exist. So I added it. Even after adding it, it does not allow me to change the program associated with it and the next time I go into file types, the MP3 type is again not on the list. I first noticed this with just the mp3 files. Now there are about 3 types of files total that will not allow me to associate a program with it. The icons all go to the default icon that windows gives if you don't have a program on your computer for that type of file. I have software for every kind of file that i am having these problems with. I also did a registry cleanup with Registry Mechanic and that didn't help at all. Please help me as I am extremely confused as to what is going on here.
(I don't know if this is worth mentioning or even a possible concern, but I am hooked up on a remote network in Buffalo that connects to my corporate office in Los Angeles, through a VPN Tunnel. I am running through a Sonicwall TZ170 router) I mention this cause I'm not sure if the connection has anything to do with the settings on my computer.
