Hi, I've got a really annoying problem. It seems that I cannot run files with the MSC extension of my indows XP. I mean, the "Services" program and all the "Administrative Tools" of Windows XP don't work. Also when I try to acces de "Hardware" tab on teh Control Panel there is the same error. The Search tool also don't work, and the Windows XP Help does not work too. When I try to run any .MSC (Microsoft Management Console files) I get always the same error: "MMC cannot open the file C:\...\Services.msc. It may be that the file does not exist, it's not a MMC console, or it was created by a newer version of MMC. Also it can be that you don't have enough permissions to open the file" (I'm sorry for my transalation, but my Windows XP is not english). So please, please, please. What can I do? Does anybody know what has happened? I haven't installed anything, so how can I repair that problem (I don't want to reinstall WXP)? Thanks in advance for any help.
