Tor keeps crashing

I've got the same problem. tor browser suddenly stopped working about four days ago. tried to reinstall but problem remains. I'm using Tor v0.2.6.10, OS X Yosemite v10.10.5 (14F27)

these are the last three lines if i start tor in terminal:

Sep 07 09:22:20.000 [notice] Tor has successfully opened a circuit. Looks like client functionality is working. Sep 07 09:22:20.000 [notice] Bootstrapped 100%: Done Killed: 9

thanks for helping Dan
