Reagor Wagnon

Hey there, I recently bought a new computer after my old one decided to turn itself in to a brick unexpectantly and wanted to redownload the game to my new computer. Unfortunately, the download link I was provided when I originally bought the game last December isn't working. Every time I download and try to run it I get an error message that it failed an integrity check and the program exits out. I'd love some help on the issue. I've attached my receipt below. Please let me know if there's any other info I need to supply. -Reagor
