I've got some problems when using the CFG USB Loader. When I start it (directly from the Wii menu), it sometimes (70% of the time) freezes at the startup. When it happens, I have to reboot the Wii each time.
It can happen 6-7 times in a row, maybe more!
I have a 4.1U Wii, using the latest version of USB Loader, which I thinkn is v68d.
Let me know how I can fix this... or if it's a normal issue...
