Intel Rapid Start Technology Manager load configuration error

On load Intel Rapid Start Technology Manager and every click on "Settings" menu entry i see that error message:

"An unknownerror occurred while loadingconfiguration information for Intel RST".

Then the applicationis running andafter adjustment,butthe laptopdoes not go away indeep sleep (RST sleep mode).

Reinstalling theapplicationdoes not help.Before that Intel RST sleep mode worked well.

And can i use this technologywithout loading IntelRapid Start Technology Manager?
I just want toturn onyour laptop anduse RST deep sleep mode later, i don't want to run RST Manager and to minimize the window to do that.

I use Windows 8 x64 on Acer M3-581TG (Intel HM77 Express), Intel Rapid Start version 2.1.0.1002.
