I don't know if you can help but here goes.
Client worked fine on my laptop 24 hrs ago. I checked and my PC still logs in OK.
But now the launcher loads but client crashes while still in the overlay screen. Nothing after that except the spinning wheel.
Included some crash reports maybe you can make some sense of this.
Many thanks.
Update: - re installed client and all seems ok .. but why the crashing? (rhetorical).
