NinjaScript Import Error

[MiniDowTrader]

I get the following message when trying to import a script:
Import failed. There are NinjaScript files in the imported NinjaScript Archive File that have programming errors. These errors must be resolved before you can import the NinjaScript Archive File.

How do I go about fixing the errors or clearing the message and importing a new script? Thanks.

I have tried all suggestions but still end up with the same error when importing the script. Could this be a problem with the script I'm trying to import?

- Could be the case or could be that you are importing a 6.5 indicator in 6.0?

The indicator in question is "CalculateValueAreaHisto.zip"
I downloaded a different indicator and successfully imported it....so it seems it's an indicator problem.
BTW, I'm using NT6...not NT6.5
