Cannot use Download script

Hi

I'm trying to download price data with the Download Script I get this message (in this case I tried to download data of the SPY):

Download compiling...........
Downloading SPY..
Bad file - can't parse Historyhistory.csv
SPY bad format

Does anyone know what am I doing wrong?

Are you trying to download from AV?
I think I got that message when I forgot to add my AV api key

Open history.csv with a text editor. If it has no valid format, it normally contains an error message from the data source.

Thank you, Dalla and jcl, the problem was the AV API key.
