Unity crashes with Oculus SDK 0.4.4

I just created a new project in Unity, imported the Unity Integration Package, run one of the test/default scenes and Unity just crashes, every time.

I'm running Unity Pro 4.6.0f3 on Windows 8.1 and I'm using Oculus DK1.

I've tried deleting Library but it didn't help (it was suggested in reddit).

The Editor.log contains some things that might be related but I can't quite understand them:

• "LookupAccountName() failed. Error 1332"

• "Task failed: Verifier Task"

• " Initializing input. XInput1_3.dll not found. Input initialized. Native extension for build target not found"

• " Device is not supported: Tracker DK (0003, 0x0005)."

• "Platform assembly: C:\Program Files (x86)\Unity\Editor\Data\Mono\lib\mono\2.0\System.Xml.Linq.dll (this message is harmless) Mono: successfully reloaded assembly - Completed reload, in 0.611 seconds Crash!!!

Is anyone else having this problem? Do you know how to fix it?

Thanks
