I also get the "Failed connection to internet" message AND the "Missing Xtra" message. It's unable to login.
I'm using Mavericks and this is my first install/run of MyVMK Experience.
Also just a silly suggestion, but why are porting VMKPal? Why not get permission from
kolyaventuri and port myVMKPal? It would probably be more stable seeing as it even runs on Windows 10.
