Can no longer get OmniFocus to launch, not from Dock icon, application folder, anywhere. Background = have several versions of OF as ran it as a trail before buying license. Also use sneaky peak on iphone. Tried to update every time got e mail prompt, and they just failed. Asked at Omnifocus support and they kindly send a description of what should happen when you download, but doesnt.

They suggested I get rid of all the old copies of downloads in the downloads folder. Which I did. Now I cant get it to launch, even though I have taken all the trashed download files and put them back where they were. I'm getting a number of error messages, depending on which of a number of OmniFocus icons I click.
These messages include:
1: "OmniFocus could not read this database, because it is not in a known format. Perhaps it has been upgraded by a newer version"
2: "the application OmniFocus 77.10.0.104538 cannot be launched - 10810"
this message comes up whichever application icon i select, of which there are several, the number ust changes depending on the version ...
Also I have noticed that there is no longer an OmniFocus image in 'devices' .
I have tried to re load the software, and it downloads, but doesnt seem to copy anywhere, just goes up in smoke!
can anyone help - I've lost everything!
Thanks
