I've sorted it, for some reason the destination was:
docs-SI-fm10-bbcsport2010-bbcsport2010-graphics panels etc.
2 bbc sport folders, one opened into the next. Thought this seemed weird so I deleted the entire folder and re-downloaded, re-extracted and only one was recreated. I don't know why this made a difference but it did. Maybe I made a folder and extracted into it the first time, I can't remember.
Take a look martin - this might well be your problem too, since it seems we were having a similar issue.
Thanks for the replies and efforts to help guys.
