Ty for the reply,i did not have the "000_toolbar" folder up,had to download it,it's a separate mod (dunno if i'm allowed to share the link but if anyone wants to get it just google 000_toolbar" ).Anyways i did download it,and after i set up the button for the thermal helper it still did not work ,no thermal window pop up.Tried deleting the interstellar mod and re-installing it with the same results. Had no issues when i was running KSP 0.25 with the window,but now...
