Brad, thanks for taking a look, in my annoyance at this problem, which I have struggled with all day, I downloaded a new copy of wp in another domain and I am now transferring the files which I saved to it.
I found the MSQ stuff and all the posts and saved them in a text editor and now mostly have it up and running.
Will completly delete the first copy of wp once done so that I can start again on the old domain and use for something else.
I did try to set it up as a multi domain but couldnt get it working right so he ho!
Thanks once again
