Hiya
Thanks for reaching out, and sorry you having issues. We have over 25 downloads each and every day, so at a guess I would assume it is a local issue for you as no one else has mentioned anything. I just did a download test and all is ok this side. Can you provide some more details with the issue your having. Does the download compete? Is it in the unzip process? etc
Permission issues can be a multitude of problems. Try unzipping as an administrator as a starting point. Check the local file permissions and user access etc.
Let us know how you get on, and we will do our best to get this up and running for you. Can you also provide you PC spec details if possible.
