Simply Silverlight Plugin in Arcade Basic

Hello,

I used TwentyTwelve theme with a plug-in called simply silverlight until now. I wanted to change the theme and use the arcade basic theme but I have some issues with my plugin which is very important for my page because i use a lot of silverlight applications.

This is the shortcode which is used to insert silverlight applications using the simply silverlight plug-in.
[simply-silverlight xap=MySilverlightApplication.xap secure=true]

However in arcade-basic the silverlight application will not be shown for some reasons. I figured out that if I use a template page and remove get_header() the silverlight applications load perfectly fine. But then of course the design will not be loaded. I figured out that when i edit the header.php file and remove wp_head the silverlight application also shows up. But wp_header is also loaded when I use the TwentyTwelve theme, so this is pretty confusing for me. I do not have a lot of experience with wordpress so maybe someone has an idea how to solve this problem?

Thank you very much ??
