Here's a Wierd One

I installed Nero OEM that came with my new HP CD52 CD-RW.

I hoped it was the full blown Nero that I’m used to but it was Nero Express.

It wanted to install DirectX9 for some video app included in Nero Express.

I clicked OK.
I’m not sure if my cheapo video card supports D9X or not.
I’m guessing not.

I instaled Nero OEM (Express) in a different directory than my full blown Nero.

From that point on, Alcohol 120% wouldn’t work.
Either CCD or Cool Edit Pro (I forget which) or both wouldn’t work either.

I had to flash an old Ghost image of my partition to regain use of those programs.
