The Title says it, i found many threads to this error but no one seems to solve it. I got Inst10 an instagram app in BB World for free but i want to upgrade to the pro version now and whenever i enter my payPal details it says "We ran into a problem processing your request. Please try again later (PS1036lq). I used a mastercard for my purchases before which worked great, but it expired last week and i dont plan to renew it in the near Future so i am pretty much "stuck" on PayPal.
I hope anyone can help me because the free version of Inst10 and also other free instagram clients are totally useless to me (No Picture Saving feature)!
