Previous purchase lost

I purchased "Pimp My Screen" on December 29, 2012. I still have the Itunes receipt for the purchase.

However, when I go into My Account purchase history, this particular purchase is not there.

I clicked on "Report A Problem", on the receipt itself, and it comes back with "Purchases older than 90 days,

see Apple Support".

I was hoping to download the app again, as it is crashing now. Not sure that it will fix the crashing problem.

Yes, I have submitted the crash report to Apple.

I enjoy the app, would rather not have to purchase it again.

Thank you.
