CR XI R2 is end of life and not the same runtime as CR 2011. There have been changes to CR 2011 Parameters so R2 is not aware of the changes.
If you upgrade to Crystal Reports for Visual Studio it may be possible. Download the VS 2010/2012/2013 installer from this link:
SAP Crystal Reports, developer version for Microsoft Visual Studio: Updates & Runtime Downloads
And test it.
If it doesn't work let us know and we'll look into it.
