There problem looks more likely on their side, that is it is not due to your local hardware limitations. I have already sent a complaint to them about this, and they said that they know about it and are working on it.
There have been all sorts of errors and anomalies in those past few weeks, especially after the recent updates (supposed 'fixes' and addition of the new competition): game low on memory, part of the game screen darkening, duplication of training drills, lots of disconnections and so on. There have also been lots of complaints posted on this forum itself.
