Well it dosn't look like I can get it to work. Getting : Error, Missing ";" in 'Class'. I'm guessing this means it does not understand the modifier... Never tried it in UDK so I guess I will have a look at that just make sure I'm not doing something else wrong...
DllBinding was introduced in UnrealScript in december 2009. The RO2 build is surely a later version of the unreal engine. It must be in there? Is it disactivated?
