We are sorry for your trouble.
Please let us know which version of CS you are using and what OS you are on.
If you are on PC and CS6 do the following:
If you go to your "Mag+" folder in your programs folder you will find a file called "MagPlusDevices.xml". Copy this file to "C:\Users<username>\AppData\Roaming\MagPlus"
Restart Indesign, now you should be able to export to Android.
Very sorry for all the problem this has been causing you!
