@WotC_Lexie:If you can, please submit your issue with logs on our bug forum!Now that's where we have another problem. Few days ago I had problem with endless "checking for updates" bug and tried to submit bug report. Guess what? Couldn't do that. Every time I tried clicked on Submit button it would just hang up there almost same way as the game was hanging on checking for updates screen.
That might be because the files you were submitting were too large. We very recently increased the file size limit, so that should prevent this from happening going forward.
