Hi, your problem come probably of an integration for security update, i don't know wich is exactly, i have the same problem and i see in my last version i have not nhelper.ex_ on my I386 directory but when i have patch it the new file nhelper.ex_ as present, so it is the upgrade, i search how i can fix it and i tell you on this forum. See ya Power is nothing without control, use Linux.
