DVobSub stopped loading

[Wormlord1442]

I used to watch soft subtitles with BSplayer (494)+VobSub 2.23 without any problem, but recently I've realized that I has stopped working.

The green arrow icon doesn't appear anymore when I load in BSplayer a file that has the subtitle file with the same name and different extension in the same directory.

After making sure in DirectVobSub propierties that it's put as "Always Load", I made several tests, and found out:

DirectVobSub still loads and work when softsubs are internal (inside an .OGM file), or when the subtitle format is .idx, but it doesn't load when format is .sub, .srt, .smi or .ssa .

I've also tested several other players (ZoomPlayer, Windows Media Player 6.4 and Media Player Classic) and they all still work (DVobSub appears).

I first noticed the problem using build 496, but uninstalling and reinstalling both BSplayer and VobSub, updating to build 500 or trying to go back to build 494 hasn't solved the problem.

Anyone knows what's happening?
