problem with srt subtitle file

I cannot view the subtitle from srt file. The subtitle context menu is disabled even when i tried to manually open it. Then I changed the srt file to sub format (using subresync of vobsub, I only installed the subtitle tools not the full vobsub) and now bsplayer can show the subtitle. What is wrong? I could always see subtitles from srt files and now i upgraded to build 499 and now i can no longer see the subttile from srt files. Also I tried to download a srt file from divxsubtitles.net (the Naked Gun 2.srt) and tried it with bsplayer and it crashes!!! can anyone help?
