I apologise for the delay in replying - moving house AND moving server meant things have got behind a tad!
I am no longer getting the 404 error, which seems to have rectified itself.
However, the slowness is driving me mad and seems to have got worse. I have to wait for at least 5 seconds for any page to load or anytime I do a refresh.
