Ta, but I fixed it anyway by copying my entrie DATA directory from teh good copy of LFS2 on my laptop to the desktop machine.
It all works just fine now.
Got LFS2-S pathed to U then to V on my desktop machine, and now it won't load.
It comes up with the error message "Could not open file :data\skins\BF1_DEFAULT.jpg"
I looked in that folder and there is no such file.
