Google custom search not working… Please help!

Hello,

I have been using the iNove for a couple months now and never got the Google Custom Search working. I enter the code in correctly, but when a visitor goes to search, it gives and error message saying “illegal request”

I know about how to enter the code, so do not tell me about that. I do not have it enabled on my site, but here is my site anyway:

Any Help will be greatly appreciated. Google has already indexed my site and I have s SEO plug in installed, just an FYI…
