I know what's wrong but how do I fix the url to file path

Permalink
Move the site from build server on fasthosts to a godaddy server .... I know but thats the clients choice.

Got the site up and sorted out an issue with the file loctions so the images - except 1 - are displaying. Cant see why the 1 image wont display it does when I edit the block.

No thumbnails are showing in file manager either even when I upload a file again.

the problem looks to be the url to the file, which is displaying
http://www.portugalsummervillas.com/files/2714/0638/6191/Casa_Plumb...
when it should behttp://www.portugalsummervillas.com/concrete/files/2714/0638/6191/C...

Any easy way to change this value?
