@MichaelJ-Grudowski Hello. You gave no detailed description of your problem but if your download sits at 0% and doesn't continue you need to temporarily disable your firewall or Windows Defender. Then it should work.
But the videos are trivial and aren't going really deep. You should try to read the manual which you can find under the help menu inside the software. It's multiple hundred pages long and describes everything in detail.
If case you have more questions please open another thread.
