Experimental not working

Hi guys im new here and i just joined up because experimental rust just isn’t working for me, i played abt 21 hrs normal rust which is fine but when i launch experimental, no servers available to me, i cant change any options, video, audio, input or game play, i can hear the crow cawing and the wolf howling though. I dont think my hardwares the problem i got win 7 home premium 64 bit on an i7- 4930k and plait 780ti graphics card. any options would be greatly appreciated.
