Failed to create component 'CrystalReportViewer' control in .Net 2005

[subgoat]

Hi, I've added the crystal reportd references successfully to version 11.5.3700 - which is CR XI Release 2, BUT the problem I have now is that the crystalreportviewer control comes up with an error when I try to add it to a form. I know it's the right version (11.5.3700) but it gives this error when I add it onto the form:
---------------------------
Microsoft Visual Studio
---------------------------
Failed to create component 'CrystalReportViewer'. The error message follows:

'System.IO.FileLoadException: Could not load file or assembly 'CrystalDecisions.VSDesigner, Version=11.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

File name: 'CrystalDecisions.VSDesigner, Version=11.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' ...

Now clearly it's got something to do with mismatching files, but I've tried to add the report view control to the toolbox from the references CrystalDecisions.Windows.Forms referenced assembly, but I'm not sure it actually does it and I still get the error. Can anyone please help with this as it's driving me bananas!
