Arity installed on G1 but won't run or uninstall

What steps will reproduce the problem?
Market says it's installed already but there's no icon in the App drawer. 
If I select it in Market, the blurbs display but the "open" and "uninstall" 
buttons are grayed 
out.
Settings:ManageApps doesn't list it.

What is the expected output? What do you see instead?
It should open. No icon to open it and Market's "open" button is grayed out.

What version of the product are you using? On what operating system?
1.15?
