It is so much fun to spend seven days trying to find a solution to the problem, yes? First, make sure your computer hardware is functioning correctly, and that your LAN router, "modem" and your ISP aren't having any issues, and that the Internet is functioning correctly. Re-installing the game software or finding some other remedy for the problem(s) ultimately won't be rewarded if they are corrupted by the computer system that you are using.....
I really truly do not want to spend two days on a full game reinstall ><
