I just update my ipad iso 6, after that monent, I can not open my mindjet document at the drop box. The message was shown "can not convert map - not enough space"...How can I solve this problem?? Help me please....
Are you trying to launch from within your Dropbox app, or within the Dropbox account of your Mindjet app?
If within Mindjet, you can try either force quitting the app and restarting, to see if that helps, or deleting the app altogether (be sure to copy any local files to Dropboz before you do this, since deletion of the app also deletes any local files), and reinstalling it.
The last resort would be to restore back to the iOS 5 version of your iPad--we will be updating our app in October, and cannot assure compatibility with iOS 6 until then. I tend to recommend waiting on installing the latest version of iOS (or Android for that matter), since the first release of any new version tends to be ironing out the wrinkles. Hope this helps
