Problems with GrimeFigther!

I bought the GrimeFighter to help cleaning my computer and to release more space. Thereby, when it starts to run, tryng to sedate the computer, as soon as start, comes a phrase that says: “Was not possible to sedate your computer!”
Please, anyone can help me? Ah! And sorry if I am in the wrong place to say that, but I am new here in this place.

Thanks
Basilio
