found the stuff, eventually got it all deleted.

When I try to re-install it now, though the app store keeps saying that the app 'failed to download' and I get stuck again.

SO I have no cookie at all at this point. Can I manually download and apply it that way?

Tried to update from 1.96 version.

At this point the app store says it's installed, but it's not - not in Applications folder, not available, and since app store says it's installed it won't let me download it.

What do I do now?
