@ geertdoornbos & @pszmyd: Thank you for responses!
I tried to do what do you suggest but; I couldn't find Modules.txt file, I looked out almost everywhere but i didn't find it... where about is suposed this file is?
Also I was reading the logs and I found references to Autofac, Lucene and Orchard.Experimental; the thing is that Autofac isn't a module (a .dll instead) and Orchard.experimental is disabled... only Lucene is active, so...
... I migrated everything but the Modules folder (I have not many custom ones and isn't to much work re-install again) then I navigate to localhost:local_port/admin and yeah, it promped me to the login form!
Compiler Error Message:

or an assembly reference?)
Line 27: Model.Header.Add(Display.Header());

I'm a newie on ASP.NET so I don't now where start to look for, or figure out if is a module problem (like do you suggested) a authentication issue or something else. Any light about what road I have to walk would be apreciated.
