Hi Paradai!
The Renderer Process Crashed-error (“Renderer process crashed: oom (-536870904)”) might be because Java or/and .net Runtime isn't installed on your system. If it is and you still get this error, please check that there are not current non-shown (Not shown in taskbar or on screen) processes of BeatCubes running. If you're still experiencing issues, please reply to this thread as fast as possible as we haven't gotten a reply yet from you.
Thank you!
