'ComponentPro.FileSystem' already has a dependency defined for 'ComponentPro.Common'

I try adding ComponentPro.Zip and the accompanying 3 other DLLs either manually or using the NuGet Manager and I keep getting the above error message. It's driving me nuts. I'm using ComponentPro.Zip Version 7.2.234.193 and VS 2012. Please help!

Please send the list of DLLs to support@componentpro.com. You may want to add nuget packages only instead.
