Failed to open file

[ryvius]

Version 1.0 RC1 Build 805

Error message:
Access violation at adress 00404300 in module 'bsplay.exe'. Read of address 00BD8000

When I moved the file into another folder, it can be opened but without sound. Moreover, the video window is extremely tiny when bsplayer open the file.
Till now, all the files with problems are downloaded via eDonkey. All can be opened and played by media player classic and bsplayer version 0.86 without problem.
