UT crash on launch

Hi, I have a problem with UT :

I could launch it everyday until all the stars challenges was completed (dunno if there’s a link with the bug).
When I click on “Launch”, it crashes and I can’t send report (the launcher is still openned without any problem with it).

I have
Windows 8.1
Phenom II 965 x4 @ 3.9Ghz
8 Go DDR3 1600Mhz cas 7
