Silverlight test recorder

Is there a tool to record and play tests for a Silverlight application in both IE and firefox? I tried to set up Silverlight-Selenium but while setting up the Silvernium.dl开发者_如何学Cl file, I get the message: "The module "silvernium.dll" was loaded but the entry-point DllRegisterServer was not found. Make sure that "silvernium.dll" is a valid DLL or OCX file and then try again.

Thanks

FeaturePack 2 allows UI Testing for Silverlight http://msdn.microsoft.com/en-us/library/gg269474.aspx
