Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi there,

I opened some boxes for some players, and when I wanted to return them, he would open trade and closed automatically. The names of the players are Demoss has given me 6 boxes Mitrhil and Grondar one Reinforced Steel Lockbox. Nor let me email them to yourself. How can I solve this problem?

Thank you.

My name in the game is Myner, sorry
