Sometimes apps get broken because of various reasons. However, since this is an Android application, there isn't pretty much to do except reinstalling, but as I said below, this needs to be done after a backup was created. In most of the cases, you can simply copy the folder of the app on the Internal/External storage in another place and everything will be backed up.
Tip: I wouldn't recommend removing the application unless you have specifically created a backup of the database with the passwords.
