Over the last 3 months quite a few people seem to be confused with downloading the video tutorials.
There are 2 links, the one in Cyan is the video tutorial, the one directly under the one in Cyan is the MD5 Checksum.
Do not download the MD5 Checksum expecting the tutorial -- the MD5 is like a UPC code on a box of cerial, kitty litter, or batteries -- it is not the product.
Download the link in Cyan and you will get the correct file. Don't even bother downloading the MD5 Checksum... you will not need it.
Note: The link has been blurred to show it applies for ANY file... not just the tutorial I picked for demonstration.
