After i downloaded some app and then update Filebox, it isnt working anymore. Whenever i open it, it stays blank at the loading screen for about 30sec and auto closed. idk if there's a app conflicts with it or it's my fw version is too old, but this has happened before with Easyplayer.
I tried to remove it though x-terminal and download lastest version but it still don't work...

I google'd and found this case similar to mine...
