bitrate info not displayed in winXP

[WRFan]

when I click on an mp3 file, the bitrate is not displayed. also when I switch to details view in a folder, the bitrate is not displayed (I also cannot sort files by bitrate, if I tell windows to sort by bitrate, it just does nothing). and on the properties page of an mp3 file the bitrate is not displayed either, nor in the bar at the bottom of the windows explorer. this problem occurred all of a sudden and I don't know how to fix this or what had caused it. If you know how to fix this problem, or what might have caused it, please post

you can find the bitrate by right clicking, properties, summary tab, then advanced, which is a real pain in the ass . . . i didn't know that it could show the bitrate, so i'm not really any help

the bitrate-bar is there (I switched it on by rightclicking on the bar and selecting it), but the bitrates themselves are not shown, although there are hundreds of mp3s in that directory. other values are shown, like the size of the mp3 files, but not the bitrate
