Making Crazyegg Heatmap Tracking plugin to work

In the past I had a crazy egg Heatmap I had a programmer embed the necessary code into my theme at [login to view URL] Every thing worked fine. A month ago, I canceled my crazy egg Heatmap subscription. Today, I renewed my subscription. Now, when I use Crazy Egg Installation Check I get the message: Script code matches instructions exactly No, the script code does not precisely match the code from the instructions page. I tried to install the Crazyegg Heatmap Tracking plugin [login to view URL] After activation I used Crazy Egg Installation Check again. Now I get the message: Only one tracking script installed? No. You have the script installed multiple times. I need the issue reolved in the following manner: 1. The existing crazy egg code in the theme should be removed 2. The tracking code should be handled by the Crazyegg Heatmap Tracking plugin. When the plugin is activated the tracking should work. When the plugin is deactivated the tracking should not work. Work will be on test site. When the work is done properly, it will be done on a live site. Freelancer should allow 7 days for testing before getting paid
