In app paid package is invalid after you upgrade!

I bought the 12 months music download package 5 months ago for approx $20 CAD and have been able to download all the songs since then until I just updated to this version, the app shows that the purchased package is gone and now I can no longer download songs! My QQ is 394604112. Please resolve it for me. I have the purchase history on my credit card bill!!!
