OpenProj - Project Management

Like Pete, I had similarly positive results at first. As a project manager who consults with numerous non-profits that are very underfunded, I thought I'd perhaps founmd a serviceable scheduling and project management alternative to MS Project. After building a very detailed project schedule over the course of a few weeks, and saving often, the file suddenly decided not to open. Couldn't open it within OpenProj, or by clicking ion the proj file name. Looking at the file in Wordpad or notepad, it looks like a mish mash of ASCII text and other characters. Don't know if a clean OpenProj file is an ASCII text file, but there was nothing that looked salvageable from a text editor. Total waste of time, which I have to eat and try rebuilding the schedule from older printed PDF samples.
