Subscriber Import had some failuresFrom campaignmonitor.com:
210: Subscriber Import had some failures There were some failures when attempting to import some subscribers. You will need to inspect the ResultData property of the result for the full details of these failures.Cant you point me to the data that's causing the problem? I'd rather not edit your plugin trying to find the right place to var_dump ResultData etc.
