I tried downloading older versions of the app, with the same error message. Any version released on or before July 20 seems to work, while those that are version 0.9 or above don't work.
Anyone know what I can do to fix this? And is there any way to get this to work without having to enable "Allow applications downloaded from anywhere" if possible?
There are specific instructions (on the download page) on HOW to install.
