So far Strike works, but I am barely able to play Assault title. It suddenly quits after Operation Umbra completion and forgets all of the progress. One time it allowed me to pass, but then failed to load first mission after Umbra series. I was playing on Windows 8.1 Lumia 920 Assault game previously, now downloaded to X3. I tried reinstall already - doesn’t help at all! What can I do with it?
