UPDATE: Nick Jones is correct. This should not be an issue if you are using NuGet....but I was also getting this message when using MvcContrib.Mvc3.TestHelper-ci. At first glance it seems like the '-ci' packages is the way to go but I decided to use the MvcContrib.WatiN package for two reasons.
1) I don't get the "Could not load file or assembly" error message
2) The MvcContrib.Mvc3.TestHelper-ci is using an old version of WatiN.Core.dll (1.3.0.4000) where as the MvcContrib.WatiN package is using a newer version (2.0.0.99)
