Recently I bumped into this error which they called it, network connection error. but i dont believe that i had a faulty connection, so here's what i did.
1. Deleted all the files in pkg folder (i know while installing, some files are corrupted)
2. run the game
3. let it download all update files needed.
.... hope this solves your problem

Well, i have done this on my 2 pc, with my isp, my brother's isp, my mother's isp, something like 30 times and have this fucking error. I have checked all file crc with my brother client and they are the same, so the error is not here.
I play other game, i have done maj for them, and all ok, so this is not isp, files ot other things, it's a server bug.
