Yeah. You're not the only one who has had this issue.
This happens because one or more of the files becomes corrupted during download. Try downloading again with a different browser and you should be good to go.
Hi. Please send an email to notmagicgames@gmail.com so I can reply with a different download link. Hopefully that one will work for you. Also, yes most people do not have this issue upon downloading. Sorry for the inconvenience.
