NEED HELP

Bought 50k Doge off a guy yesterday.  He sent them on Coinedup.  They were there for 24 hours.  I signed in and out of Coinedup multiple times.  They were always there


Turned off computer turned it back on when I got home.  Tried opening up coinedup many times but browser would not open.  It finally opens I sign in.  I now have 0 Doge

The one thing that I have noticed is that my user ID up in top right of coinedup is now different than it was when I would sign in and could see the doge in account.    

This latest time that I signed into Coinedup I used Chrome.  All other times that I signed into Coinedup and could see my doge I used IE.    Only reason that I used chrome this time is because IE will not open Coinedup at all


WTF???

HEEELLLLPPP
