System.IO.FileNotFoundException: Could not load file or assembly... (.resources)

On my ASP.NET Web API i have a method that parses some data from email messages using MsgReader. It works OK, but after a while it starts to throw following exception:

System.IO.FileNotFoundException: Could not load file or assembly 'MsgReader.resources, Version=2.1.3.0, Culture=en-US, PublicKeyToken=47f99f3a9a2648df' or one of its dependencies. The system cannot find the file specified.

After i recycle application pool, it works again (for a while) then at some time the error repeats...

I tried with assemblyBinding

  <dependentAssembly>
    <assemblyIdentity name="MsgReader" publicKeyToken="47f99f3a9a2648df" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-2.1.3.0" newVersion="2.1.3.0" />
  </dependentAssembly>

but no success...

I think the problem the problem is with Culture? Because as i see in error the Culture is en-US, but in MsgReader package there are only these cultures:
