@rsawoseyin: ok, so you told me that you have multiple email accounts on your phone...
In this case, make sure you are logged into the primary account in the Google Play app when you start DroidScript (you can set which account is active in the app settings)
Also you should have installed DroidScript under that same primary Google Play account, so if you think that you did not do that, then you should backup your apps via email and then uninstall and re-install DroidScript making sure that your primary account is selected in the Google Play app when you do the install.
If you are using the latest beta, then you should still install the current version that is on Google play first, but then overwrite that version with the beta version found here -
Make sure you have a good internet connection while you are doing these things.
