Problem with MP3 file on Nokia 5130 Express Music?

I'm playing a file on my Nokia 5130, but the duration is displayed as 7:03 instead of one hour and fifty eight minutes. Plus I can't fast forward after 7:03 because it plays the next file, even though the file I'm playing hasn't been finished yet. My software version is 07.91 and the mp3 file size is 26.9 MB.
