[Phoenix 3.11] Connection Problems?

Hi !

My EMU was working for 1 month on a public hotel wich i host. It has up to 20 Users. Its a little Hotel.

Yesterday the connections are down :D

The EMU starts perfectly.
The first User can connect on the Client but when he try to load any room its stucks in the hotelview. Nothing happens -.-

In the execptions.err file i found this:

PHP Code:

29.07.2013 17:59:36: Error: System.NullReferenceException: Object reference not set to an instance of an object. at ns0.Class33.method_1(Class16 class16_0, String string_1, Boolean bool_13) in C:\Documents and Settings\Kenny\Desktop\Phoenix v3.11.0 (14986)\Source\ns0\Class33.cs:line 178 at ns0.Class257.imethod_0(Class16 class16_0, Class18 class18_0) in C:\Documents and Settings\Kenny\Desktop\Phoenix v3.11.0 (14986)\Source\ns0\Class257.cs:line 14 at ns0.Class16.method_13(Byte[]& byte_0) in C:\Documents and Settings\Kenny\Desktop\Phoenix v3.11.0 (14986)\Source\ns0\Class16.cs:line 471
