Paid for but not getting upgrade?

Hi. Ive been using the free version of this app for quite some time. I really like using it... But decided to upgrade to the $5.99 version (which will end up costing me about $9 CAD). It has not upgraded? Still asking for payment even though it went through. How do I get my upgraded version???
