Web Analytics Module

I am trying to integrate the web analytics module with iis7. I have compiled it and followed the instructions shown in http://learn.iis.net/page.aspx/480/sample-web-analytics-tracking-module/ but when I pull up the IIS manager, event viewer is showing the following error:

IISMANAGER_ERROR_LOADING_PROVIDER_TYPE

IIS Manager could not load type 'WebAnalyticsModule, WebAnalyticsModule, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c6b7132bcfe43312' for module provider 'WebAnalyticsModule.WebAnalyticsHttpModule' that is declared in %windir%\system32\inetsrv\config\administration.config. Verify that the type is correct, and that the assembly that contains the module provider is in the Global Assembly Cache (GAC).

Exception:System.TypeLoadException: Could not load type 'WebAnalyticsModule' from assembly 'WebAnalyticsModule, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c6b7132bcfe43312'.

Process:InetMgr
Connection:WIN-5RSAJTAG8FR\Administrator

Any idea where I might look to track down why IIS cannot load this module?

Thanks,
