Upgrade to 1.1.0 successful but unable to access backend

Update on J1.5.25 was successful but twice it asked for scientific update and I performed it twice. Once that was complete a blank page comes up when I try to access the mobilejoomla component in the backend. Any ideas? I get no errors from joomla just a blank page. Maybe I can check the logs to determine what is happening?

Thanks,

Try to redownload and install MJ1.1 (in few hours after initial release there was a minor fix of backend blank screen). As to twiced scientia mobile install, it's quite strange, we will try to get reason and fix it.
