Are you using LastPass?
From our Q and A page: http://mobilinc.com/support/commonquestions/
"MobiLinc for Android is crashing after working for months. What's happening?"
Please check if you are using the Android 3rd party app called LastPass. LastPass issued an update in March/April that actively interacts with other apps on your Android device. Some apps, like MobiLinc, do not react well to other apps interacting with their UI.
LastPass has an option to disable interaction with other 3rd party apps. Please disable LastPass for use with MobiLinc.
