New Beautiful Sweet FX

[Smilinjack]

Yes, I tried repairing DX and .Net to no avail. I finally removed SweetFX and the crashes went away.
I then reinstalled IE 10 via MS Update and ran without Launcher crashes.
SweetFX is definitely the cause of the crashes, at least on my machine, after applying the MS updates in early March. I assume it's got something to do with DX after the update as DX11 was updated in association with IE 10.
Result.. SweetFX will run if the March updates are not applied and will cause Launcher crashes if run after the updates.

BTW, thanks for the reply.
