I think I had this bug before after updating Pokemon Online one time that crashed my Client when logging on. Try removing Pokemon Online completely. Note this will remove your alts list and teams I imagine but it may fix the problem for Moogle's Client scripts for Windows users. Please be cautious when doing this by the way. Also backup your teams and alts with their passwords before doing this. Do this at your own risk. I'm not fully sure if I did this before many months ago. But I hope it helps. - Un-install Pokemon Online - Delete the hidden files in "C:\Documents and Settings\[your Windows log in name]\Local Settings\Application Data\Dreambelievers" (I don't know why there's a folder called "Pokeymon-Online" with "Pokemon-Online" there though. Those are the only folders you should need to delete there.) - Delete the My Documents folders in "C:\Documents and Settings\[your Windows log in name]\My Documents\Pokemon Online" as well. - Re-install Pokemon Online and add the script. I don't have a Mac so I'm unable to help but I hope this fixes the unknown crash problem with Windows users.
