ebapi.js not being load in mc9090

Just found that the ebapi.js is not creating the EB class, when in the mc9090 I put a window.onerror and EB is undefined

<script type="text/javascript" language="javascript" src="EBAPI.js"></script>

If I replace the content with alert(1) it shows up, so the file is being found, in my PC in Chrome it exist the EB when I run the page, but in MC9090 seems to be a problem to create the class
