OpenOffice not opening

[dlmos]

When I try and run any of the OpenOffice programs I get this error:

An exit code of 126 was returned from openoffice.org-2.0

/usr/bin/openoffice.org-2.0: line 2: /usr/lib/openoffice.org2.0/program/soffice: No such file or directory

/usr/bin/openoffice.org-2.0: line 2: exec: /usr/lib/openoffice.org2.0/program/soffice: cannot execute: No such file or directory

I check using Nautilus and the file it's looking for isn't there. Is there a setup program that needs to be run? I thought that as it was packaged with YDL5.0 it would run straight out of the box. Any help would be much appreciated.
