My son keeps getting an error message when loading Terraria

Costume Quest,Brothers:A Tale of Two Sons,Alan Wakes Nightmare ,State of Decay and Terraria are all good but Minecraft is still the best because it keeps evolving and getting better.

Some other people including myself have posted on the Terraria forums about this problem. Hopefully it will get fixed soon, my son is quite upset as he loves playing Terraria online with his friends.

I keep getting an error message and the game will not even load....message says server problem

My son is having the same issue with the error message. It seems to have begun when he (unwisely even at 9 yrs old) hit a "repeat" command when playing, teleporting "all entities" to the same place. All entities in the game began flashing on the screen
and he could not stop this. Since, he gets the error message 0x80040200 whenever loading and cannot play the game. We've tried the 10 second shutdown, still no go. Please help.

Thanks for your help.

Okay, next question. I want to transfer some money to the account of my son. I've transferred some, but now if I want to transfer some more I get an error message??

Then I made a purchase request from my sons account, but when I try to approve it, I also get an error message???
