firstly i tried to purchase rsharks, that worked but when i run it , it walks to the spot then its spamming error messages, it was only 2 dollars so i tried to buy another one but at every script i try to buy paypal somehow doesn't complete the transaction, any idea why? 

Happens sometimes.. It's probably because your Paypal is unverified but just try again later and it will work

alright, the message is in dutch but i'll translate it: we can't process your payment at this moment

and underneath: go back to the webshop and select another payment option.

 

@disboyer i hope that's the case, i only made paypal 2 days ago and confirmed my bank account today so i don't have any experience with paypal, thanks anyway
