NHibernate, NHibernate.Linq, and FluentNHibernate? Throwing error

I had the following error at previous question:

Fluent NHibernate? Am I doing this correctly?

But, now, when I call the function:

LoginRepository login = new LoginRepository();
var allLogins = login.GetAllLogins().ToList();

It throws an error of:

Could not load file or assembly 'NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The source of the problem is NHibernate.Linq. The FusionLog is as follows:

I used NuGet to get the latest versions of NHibernate, NHibernate.Linq, and FluentNHibernate.

Can anyone lead me in the right direction?

Thanks again!
