When I click on the stepmania.exe in the program folder it instantly crashes. I think I followed all of the steps to have it and the new updates and songs. Unless I have missed something?
What OS are you using? Make sure to follow all the steps of the 2.1 update and then install the special version. If the trouble persist, I can try to upload a base game with everything updated except for the songs that you wil need to install separately.
I am using Windows 11.
