@DeroDewan The free and premium BAS applications are identical except for the premium label. All premium features are available in the free version if you have purchased the premium version.
But if you want to download the premium version, you can do so in your personal account at https://bablosoft.com/personal/license/BASPremium,
but the old version is currently available there. (you need to wait until they update)
bablosoft has never mentioned the possibility of downloading any old versions of BAS. Change the versions in the link, older or newer versions may be available for download.
Export your spreadsheet as csv file, than import it to BAS as a resource and set it to use each line 1 time (it is default setting I think). That way each thread would take new line from your csv file in run mode or as compiled bot.
