The package I downloaded had no crack, but I found something that solved my issue.
I'm allowed to post a link to the crack to help someone that would have the same issue right ?
Here it is :
Crack : AdF.ly - shrink your URLs and get paid!
(Game from https://btdb.to/torrent/9omgxvOMqpUjXg1WxnqrtYDWo5gDg3twOrK.html )
Inside is a AlphaROMdiE.exe, launch it then drag/drop the game exe file (in my case SiglusEngine) on it
A new .exe will be created that you can use to launch the game
