Cannot launch/connect to my database since i updated windows from 8 to 8.1

Question

Hello,
Firstly, don't be surprised, i don't speak english very well. Yesterday, everything worked. However, since i updated windows 8 to the 8.1 version, it doesn't work anymore. When i launch sqlplus and i try to access to my database, i get the error below:
D:\>sqlplus

I tried what you said. Here are the results:
lsnrctl services BDVINOU

The result in the listener.log file after the previous command execution :

And the result in the listener.log file when i try to connect to the database using sqlplus:
Fri Dec 13 13:54:24 2013
13-DÉC. -2013 13:54:24 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=BDVINOU)(CID=(PROGRAM=D:\app\vincent\product\12.1.0\dbhome_1\BIN\sqlplus.exe)(HOST=VINOU-LT)(USER=vincent))) * (ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=51407)) * establish * BDVINOU * 12514
TNS-12514: TNS : le processus d'écoute ne connaît pas actuellement le service indiqué dans le descripteur de connexion
And when i try to get data about the status (lsnrctl status), i get:
