Issues with VQmod installation

Hi,

I am having major issues trying to reinstall vqmod on my site: sittinginatreecrafts.co.uk. I have uploaded files and changed permissions but am getting an access denied message when I attempt to install. Any other pages I try to view now come up blank.

Is there an easy fix to this that I am missing or do I need to reinstall everything including opencart from scratch?

Any help or advice would be really appreciated,

Thanks in advance
