Thanks again for your help...
Would you suggest that this is as I thought then, a timing out issue?
Where would I find the instructions you refer to, this came on a pre-bundled site so am still finding my way around the detail on here - Is it as simple as downloading the zip folder from here?
Also given my site is hosted on a shared server, would this cause any issues with timings or so much as in, being able to amend them?
Many thanks once again,
Del
