.srt file doesn't work in my DivX player

Hello guys,
i have a foreign movie in .avi format and everything is ok when i play it. The only problem is when i downloaded its subtitles in .srt format it doesn’t work. Even when i choose the specific srt file, in the screen doesn’t appear anything. Can anyone help me please?

Make sure the srt file is named EXACTLY the same as the AVI and that it is the same folder
