@Tantric: nop turning on with an older version doesn’t works… Ratat0skr tell us that possibly is Avast 6 (new version) that upgrades the next day of WiiMC does it. If it where Avast, WiiMC works perfect. I inform you about this issue with Avast 6. Thanks for all
@Ratat0skr: first one i have to tell you that your name is specially difficult to write 😛
In other way, I try uninstalling Avast but before this, I try to switch options on it because possibly this workaround is customizable
