Keep in mind that crashing is often related to poor communication w your wifi router. So another thing to try is a router reboot.
But im also convinced that EA has two different paths for logging into their servers. Because some events I have no probs w crashing, and then the next event has the exact same pattern of crashes: two bart screens, close and reopen the app and then it connects right away. Same pattern every time; then that event ends and so does the pattern of crashing. It's too consistent to not notice.
Regardless, they dont seem to do much to correct it. Good luck working it out.
