Thanks for getting back to me woodent. Problem solved though – there was a problem with the wordpress installation (it was also causing issues with other plugins) so I done a fresh install and all is now operating as it should.
I am having the same problem. Now I have enabled PHP5 it will still not let me activate the plugin and yields pretty much the same error message as above
