titanfall won't load after new update but it says it is 100% complete

ownload and install the latest version of Origin at www.origin.com/download (and make sure you have your Origin account ready as well)
Close the origin client and go directly to you origin folder  C:\Program Files\Origin Games. Then add Origin into windows firewall and anti-virus software's white list, and set the permissions for this folder to /writable. Run the origin.exe in this folder with a rightclick -> run as administrator.  

Power-cycle your modem by unplugging it from the power source for at least 30 seconds.

Try to deactivate your firewall/antivirus software and/or check the online ports of your connection:

TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300
For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.

Please let us now, if this problem after this workaround still exist.

I'm having the same issue and your suggestion did not work.

http://help.ea.com/in/article/manually-uninstalling-origin/

Went through with the helpdesk and this is what fixed it for me.

Did about 20 other things to get there too, clean reboots, lower UAC settings. But this is what did it for me. 

Manually deleteing origin and re-installing.  (not auto uninstalling and re-installing, which didnt work)

Hope it helps!

I just re-imaged my PC.  Works now.
