[Info] Script Errors on the Launcher

Hi guys, I'm quite new to the Sims community here, but I've decided this problem is the end of my lurking days.

My problem is similar to the others in this thread.

I've updated java, flash player, windows, origin, the sims, downloaded adobe air (whatever that is), checked internet explorer, although since I can log in I expect IE is doing its job.

Answer to Questions: 

What's your operating system ?

Windows 7

What does the Error Part and the URL Part of the message say ? 

Line: 1014 

Char: 4

Error: Unable to get property 'length' of undefined or null reference

Code: 0

URL: http://launcherapi.thesims3.com/launcher/home.html?launcherLocale=en_US&launcherCountry=ID

What happens if you press Yes/No?

Not a goddamned thing. 
What version of Internet Explorer are you using (the launcher is hard coded to use IE): 

version 11.0.9600.17107
Are you using ad-blockers and if so, which one ? 

On my Chrome? Adblock Plus and Adblock. On my laptop? None. 
What country are you in?

Indonesia

Issues: 

1. I can't access any custom content (paid or otherwise), either by store or by mods because the Launcher would not show any installed/downloaded content. It is entirely blank. I did not have this problem when I was playing through Steam, but I digress. 

2. I can't play the game because every 10 seconds the game would automatically minimize to show the error message. 

Any input would be appreciated. Thanks.
