Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.17929 

it seems that the problem is in the SQL communication but as I used the automatic installer,so, i do not setup anything in SQL.

I read in another post mentioning .NET my is ASP.NET v4.0 (i install 4.5 but only 4.0 shows up to me).

Can someone give a hand with that? Ty! =D

I reinstall and now is working.
