Due to a new hard drive on my PC, I needed a refresh of the download link as I had not saved the file which was my mistake. When I contacted Heyd manuals team it was done almost promptly and without any questions. Great support and service was not sure they were going to do this at all, but it was done within minutes and I had the manual on the new PC, awesome service.
