BSplayer hangs up when loading .avi movie

[djargad]

I'am using BS 0.86.500.It was working normally with .avi files until one day when i tried to load an.avi movie it hanged up.It was loading endessly.
I tried it with many movies even those that worked before that problem.
The only way to shut it down was to Alt+Ctrl+Del to open the task manager and end the application.As a result i came up with the error report which was:
szAppName : bplay.exe szAppVer : 0.8.6.500 szModName : qasf.dll
szModVer : 9.0.0.2980 offset : 0002fd96

I have a slight thinking that the problem might be in that qasf.dll
where can i find a new one???(i mean if you know which application uses it appart from bs)

I have also tried to uninstall and installl older versions of bs but problem remains

Notice:All other kinds of videos play normally (.mpeg) except for divx encoded (divx 5.0.5)

Pleeeeaseee heelppp!!!
I don't wanna stop using BS :?
