Dolphin taking too long to start

[guiboos]

Hi,

I have made a fresh install of windows 8.1. Then I installed Dolphin 4.0.2 and now I have two issues.
1) When I click Wiimote or GCPad buttons it takes about 1 minute to open it.
2) When I start a game it takes the same time for the game starts.

What can I do?

Thank you
