I've contacted the StackIdeas folks. My EasySocial account isn't available right now, so I can't get the 1.2RC release to test. Hopefully, that will be cleared up soon.
In the mean time, from the error you mention, simply disabling the "Import Cover Photo" option should prevent that error message from blocking things.. of course, there may be another error that crops up after that, but if so, let us know.
I hope that helps,
Alex
