Hi Mauro:
Sorry for the problem.
I have seen this a few times before. Not sure what the problem is.
The error is with the SlimDX library which LOGic uses for the voice keyer and spot announcement. It is already installed on this machine, so you can safely ignore the error.
If you ever needed to install SlimDX, for a new installation on a new computer, and you still get that error, you can download it and install it manually.

Let me know if any questions.
Tnx for using LOGIc.
