Hi, can you provide us with a HJT report to discard any antivirus or parental control software messing with the download?

Download: https://sourceforge.net/projects/hjt/files/2.0.5%20beta/HijackThis.exe/download
Run HijackThis as Administrator, choose "I accept", then "Do a system scan and save a log file". After a while a text file will open. Copy everything, put the log on https://paste.ubuntu.com and give us the link.

This is on a basicly brand new MacBook Pro running Mac OS without any antrivirus or parental controls enabled.

I have just tried deleting the libraries directory to force it to try to re-download the libs but that didnt help.

Leaving the Beta version of the launcher fixes the issue and the game launches as expected.

Thanks for the bug report! This issue will be fixed in the next beta.
