Subtitles won't show up on DivX movie

[Snapper]

Hi,

although I've read a bunch of threads I couldn't find a solution to my prob:

Downloaded a DivX 5 movie with corresponding subtitles contained in two files: .idx and .sub.

After opening the movie and choosing 'Load subtitles...' the subtitles don't show up, however, and neither is anything clickable on the 'Subtitles' submenu (it's all greyed out).

'Subtitles disabled' is unchecked as well. I also fetched a current version of BSPlayer ('1.00 RC1 Build 807' at this time) only to realize that it's not an old bug being fixed already.

That's all hints I was able to find by searching the forum. Anyone out there having a clue what the cause for this is?

Thanks,
