System.Web.HttpException (0x80004005) - FluentValidation.AbstractValidator

Hi,
I have a problem with this error.
I refer to the version 2.4. The site lies from a provider that has not changed anything.
I do not understand, i do not modify any files.
I tried deleting all files to reinstall them, to compact the database and see if there was something that did not work.

How can this happen, unexpectedly?

Thank you very much.

The log is:
Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

Thank you Andrei.

I resolve. I write the step for other users.

1) Delete FluentValidation.3.x, FluentValidation.MVC3.3.x from packages directory
2) open project with visual studio and remove and replace the reference of FluentValidation.dll and FluentValidation.Mvc.dll
3) ricompile the project and open Prepare.bat and deploy.bat
4) substitute and replace of your original deploy files ( on your web site ) the folders: bin, Content (attention of directory IMAGE !!!), Scripts.
5) find and replace of Plugins\Payments.AuthorizeNet -> FluentValidation.dll
6) find and replace of Plugins\Payments.Manual -> FluentValidation.dll
7) find and replace of Plugins\Payments.PayPalDirect -> FluentValidation.dll
8) stop iis and restart iss

bye bye

Excuse me,
i miss 1 step:
Replace the Fluent with new library, that find on new version of nopcommerce source
for example on 2.65 version:

FluentValidation.3.4.0.0
FluentValidation.MVC3.3.4.0.0

on directory packages.

Bye Bye
