i want to import a zip file with a indicator / strategy

i get the following message
==============================================

you have custom ninjascripts on your pc that have programming errors
the errors must be resolved before you can import a ninjascript archive file
=====================================================

you see there is no suggestion with strategy or indicater has an error

do i have to delete or start over again to reinstall ninjatrader
or is there an other way

please how can i solve this
