E-Drawings Pro for Android - lost license

Hello,

I bought and installed e-drawings on my android telephone early last year, but I uninstalled it earlier this year, when I was low on available space.

Today, I decided I wanted to use it again, so I opened the app store and it identified that e-drawings was 'purchased' on my telephone.

I clicked install and waited, and now I have e-drawings installed, but not the Pro version. If I ask it to upgrade to Pro, it wants my credit card details.

How can I convince it that I have still bought it?

It's only £4.90, I know, but even so...

John
