Color, Pictures, Revolution Slider problems

Hello,

I’m creating a Website, with your theme. Its a wonderful theme first of all. I created already other Websites and they look great, but now I have a serious problem: I can’t change the default colors . I can’t delete the pictures in footer that I put and now I need to deleted. I deleted from the Media library but the picture still appears in the footer. Also I can’t see the Revolution Slider….
What’s wrong?

I’m using the latest WP version and your latest Version of your theme. The WP is on a Windows server with IIS, not on Apache for this client.

I uninstaled and re-instaled the theme several times but the problem persist. !

Can you help me please. Its critical for me to get this working correctly and is very urgent.

Thank you.
Best Regards
