I already tried the procedure indicated in the comments, I mean:
1. Exit Origin completely. You can do this by right-clicking Origin in your system tray (near the clock) and selecting "Exit"
2. Open Internet Explorer (this will only work with Internet Explorer, not other browsers). Enter the following address into your address bar and press "Enter/Return"
C:\ProgramData\Electronic Arts\EA Services\License
3. Delete the file named either 71067.dlf or 70619 or 71069.dlf
After this perform a clean boot by following these steps:
Press and hold the 'Windows' Key followed by the 'R' key to open up a prompt window.
In the prompt window, type 'msconfig.'
When you have finished typing, click OK. At this point, you should now see the multi-tabbed System Configuration dialog box.
Click on the 'General' tab
Choose the 'Selective startup' option
Uncheck the 'Load startup items' box.
Open the 'Services' tab.
Check the 'Hide all Microsoft services' option at the bottom of the tab.
Click the 'Disable all' button.
When prompted, restart your computer.
BUT, these "71067.dlf or 70619 or 71069.dlf" were not THERE!, only a 1010958.dlf...
Anyway, after performing this CLEAN BOOT, my pc almost crashed, it won´t restart properly.
The only thing I didn´t tried was to uninstall the game and download it all over again, that´s because I think that, as a consumer, I deserve a better solution. Now I´ve been waiting all day long to find an avaiable chat and nothing untill now... And the time goes by and I can´t play the game I paid for. The double xp days are coming, I bought the premium version and all I can do is watch my static stats on battlelog... Trully dissappointed about EA... Gustavo (Brazil)
