Convert App Store license to direct download license

Hello,

i bought TaskPaper from the Mac Appstore recently, but now i would like to use the software on another
computer of mine which has no Appstore access (intentional). Apparently the app does not have
a license key, so i guess i trapped myself in a dead-end. Or is there a away to convert my AppStore
version into a direct download version without paying twice?

Yes, please email me directly at jesse@hogbaysoftware.com
