Finding the file is not the issue, downloading the file is the problem, please see attached image.
Click on the file from the lab and demo files, click on the commercial, select save as , then the download box sits there on 0% and doesn't move
Can you please send me an email to - and I can transfer the requested file to you.
May I ask the browser you are using? Selecting the link to download the files should provide the save dialog to save them to your local machine.
You mentioned your tried the commercial files.....since you are using the student edition, you would need to select the Training Files....not Commercial.
