Ok i deserve a slap, i must have been knocked on the head at birth. I have 2 Wii's, one mine one a friends. I attempted to install the HBC on my friends without thourghly reading the forum instructions . I installed the HBC successfully on the system then after the final restart i was prompted for an upgrade. Without knowing i accepted and upgraded to what i now know as version 4.0. To top it off for some reason i removed the HBC after the upgrade with intentions of doing a new install and now i cant get it to work. The twilight hack wont copy over to the Wii memory. I have formated the system memory thinking that would clear all and i could start a fresh but this hasnt helped. When trying to copy over the hack it says it is already there or that the file cant be moved. I have since attempted to do the hack on my own and it went all well, forum instructions followed this time obviously. I have been looking for a thread that instructs how to downgrade from ver 4.0 but as far as i can see this is not possible yet. Please can some one help out as i dont want to let my friend down.
