Trapped Server sudden error

I was playing on my Pserver when I got killed, and then instead of showing the death page it went straight to load error, retrying and it was giving me this error;

System.Collections.Generic.KeyNotFoundException: The given key was not present i
n the dictionary.
at System.Collections.Generic.Dictionary`2.get_Item(T Key key)
at db.Database.GetNews(Account acc) in C:\Documents and Settings\mike\Desktop
\rotmg_svr-master\db\Database.cs:line 61
at server.char.list.HandleRequest(HttpListenerContext context) in C:\Document
s and Settings\mike\Desktop\rotmg_svr-master\server\char\list.cs:line 61
at server.Program.ProcessRequest(HttpListenerContext context) in C:\Documents
and Settings\mike\Desktop\rotmg_svr-master\server\Program.cs:line 104

Any help is appreciated
