Actually, you had nothing to worry about… I accessed the IP through VPN and it seemed to just redirect to that Amazon link. It wasn’t your IP, it was just the Roblox Amazon thing.
Download the zip file from there, and extract it. You should find a file named “RobloxPlayerBeta” inside of there. You can drag that file to the folder in: C:\Users\YourUser\AppData\Local\Roblox\Versions\version-758ce9d32bfd41b2
(if you can’t find the AppData folder, press “Windows + R” and type %appdata%)
You should get a popup that says something like: “RobloxPlayerBeta.exe” already exists in this folder, what would you like to do? Click the replace file button and wait until it is done
After doing that, you could try running Roblox again
