I see here no problems with 2.2. The data exchange takes place via UDP. The DCS version is not important to me as Ikarus developer.
It can only be because our export script, that develops McMicha, is installed in the wrong place or you use a older version. Please check that for 2.2.
It will soon be easier with DCS 2.5. Then, we will only support 2.5 for future updates from Ikarus and our export script.
