It looks like you're trying to load these characters through the browser's address bar, like "VL8LIKZ7fPQ". Probably you have some problem in the logic of the script.
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.
