Fixing dll for the latest version of mt4

Hi,

I need developer to help me to fix tradeswitch.dll that working on the old version mt4 but not working well in the latest version

It's dll that write registry and read the registry value.

the function is :

   string   ReceiveSignal(string Name);

   int       SendSignal(string Name, string Value);

   int       FlushSignal(string Name); 

For the ReceiveSignal is to read the value and delete it. it's 1 by 1 not flush (all, only delete the read value).

I need it ASAP.

Thanks.

 Regards,
