Error loading .ogm video with .idx + .sub files (subtitles)

[IGC]

I have a problem, everytime i try to open an ogm video that has as supporting subtitle files an .idx and .sub files. The bsplayer gives me an error. If i press the continue botton and then the play button, it will start to play it normally, with subtitles and all. But i don't know why it gives me the error. If I delete the .idx file it plays fine, but then i cannot see the subtitles.

The error it gives is the following:

BSPlayer v0.86.499, Unhandled exception at EIP: 004A8E59
