Yes, I read it but I must do something wrong.
I am using an task planner from my webhosting provider (Ovh) because I can't use Cron jobs.
I followed the instructions of the video, but I can't paste the command, just put the location of the script (www/goxgrab/mtgox_update.php) in my case..
Very strange.
I think I will wait the new version, it will be easier because I don't understand why it is not working !
