I've been playing this game since release date.. first on a PS3 and now on a Macbook pro. Never had any issues whatsoever. However, since the new patch on April 17th/18th, I haven't been able to download it. I keep having this error

Unable to complete version check.
[30410][30607][10009][19900][12169]

Before some of you tells me to delete that mysterious folder, I've already done it. 4 times. It didn't work. I still get the same problem.

This is what I've tried so far:

1) Re-starting my mac.
2) Re-Starting my router.
3) Deleting my internet settings completely
4) Deleting the application folder (according to a moderator on this forum. <-didn't work).
5) Tried to see if it would work using my phone's internet
6) Tried getting in touch with SE chat support (They couldn't do anything for me. I have a picture of this chat, I'm quite frustrated by this).

Any ideas how to fix this problem? Again, It's the first time I'm seeing this. Clearly, they did something on that patch.
