after changing the properties to compatibility mode and run as administrator, it worked fine.. but then, when i tried uploading a new library folder (for music uploading) it shutsdown again.. i noticed that the new folder that i added in the library contains other file types other than .mp3 (such as .flv & itunes folder, etc..) so what i did was just erased all the other files, other than the mp3's and bearshare worked once more...
