This is strange, do you still have the installed copy of HiveMind?

First of all HiveMind is being developed as a cross-platform application for both mobile and desktop environments, so we actually have "PC version of the HiveMind", but there are no rpms or debs available at the moment. We are planning to provide them in the late spring. In the meantime you can use version from the mercurial repository. If you are interested we will create a corresponding manual on how to install and run HiveMind on your Linux distributive (Windows installer is on the way to production mode, if you interested in that platform)

HiveMind uses modified FreeMind fileformat. This means that all the mind map that we made in the HiveMind will be opened in FreeMind and vice versa. But there are some limitations: FreeMind does not support link labels and node/label formatting propagation, HiveMind on the other hand does not support arrowlinks, images and may be some other less needed stuff (if you think that this feature is really needed to be implemented be free to post a bug/feature request on the project tracker).
