Trying to update MCA and various other mods. I've been told that the latest MCA requires the Master Head Pack. I've got both but when I try to unpack MCA I get this warning:

! C:\Users\Connal\Documents\Morrownd Mods\Morrowind Comes Alive\Morrowind Comes Alive-6006-7-0.7z: Cannot open C:\Users\Connal\Documents\Morrownd Mods\Morrowind Comes Alive\Morrowind Comes Alive-6006-7-0.7z

Likewise when I try to unpack the head pack I get this:

! C:\Users\Connal\Documents\Morrownd Mods\Master Head Back\Master_Head_Pack_X.7z: Cannot open C:\Users\Connal\Documents\Morrownd Mods\Master Head Back\Master_Head_Pack_X.7z

This makes updating things difficult.
Any help would be greatly appreciated!
Thanks!
