The issue can be resolved if you have either Avast, AVG or COMODO firewall installed - if you have none of those 3 then try adding the PS2.exe and PS2 launcher through your antivirus/firewall exception list.
if you have 1 of those 3 then Avast is simply adding it to exceptions list, same for AVG, with COMODO you goto "Defense+" then to "Defense+ settings" the option your looking for is "Deactivate the Defense + permanently" Restart and all should be good.

No need to deactivate that permanently. Just go to Defense+ settings--->Execution Control settings and add Planetside2.exe to the exclusion list. (Possibly launchpad.exe and awesomium.exe too)
Yeah, I did that the other day when online and it wouldn't let me on until I disabled it totally and rebooted.
Others might have more luck but I will keep looking at it time to time, enabled/disabled, and see if PS2 eventually allows it.
