Hacking WiiFlow starts Disc instead of USB Game

[ShadyGT]

Hi,
i softmodded my vWii about a half year ago when i bought my WiiU. Usb loading worked fine.

Now i wanted to play a Wii Game again, but WiiFlow doesnt load it.
If there is a Original Wii game in the drive, WiiFlow launches the disc. If there isnt any disc WiiFlow freezes at about 15% loading.

I tried Usbloader GX but it cant recognize my USB stick (Wii Flow recognizes it).

Im using the newest WiiFlow and Usbloader GX.
My Stick ist formatted to NTFS.
It worked with the same Stick a half year ago.

Can anyone help me pls?
