Hacking game list issue with usb loader 1.5

[MrPook]

Hello,
i'm using usbloader 1.5 from Waninkoko since a week a everything worked fine until yesterday.
I'm using wbfsguiv10 from calimero to upload games and now the list of games won't show.

Still i'm able to navigate and select a game but only through images displayed on the left part of the screen.

By the way, everything is fine with uniiloader...

Any clue why it doesn't want to work anymore ? (tried special caracters but nothing changed...)

Thanks in advance.
Pook
