I'm also running this on a mac, if that makes any difference.

 

Thanks,

This did not help me. It freezes at the load screen. Same problem.

Delete the zip and download it manually.

I have done that multiple times. It appears as a joined.srg file? I place it in the libs folder still does not work

 

Dont put the srg there. Put the zip.

As long as it's not a corrupt download it should work.

Your error is telling us it's corrupt.
