Corrupt Files or Earlier Version

I'm having the same problem, and I'm having it over and over again. I've lost almost two days of work because of it. This is not the first time this has happened, but every other time the projects were so small that it wasn't such a big deal to just redo them. This time, I've recreated the project three times. The very first time, I saved the project, then later tried to reopen it and got a message saying the file was corrupt or created in an earlier version. I'm using Replay 360, and it's the latest version. Ugh! An IT guy and I tried to figure out the problem, ran updates, uninstalled and then reinstalled the whole Articulate Suite, but still no luck. Eventually, I recreated the whole project, which took a very long time, and about five minutes before I was done with it, a window popped up on my screen saying Articulate Replay was stopping and closing down. Then it closed down. I lost the file completely, because I had been in the middle of recording something and hadn't had a chance to save it yet. The third time, I recreated the project again, but this time I WAS able to save it. Then, about five minutes before I was done with the whole project, another message popped up saying Articulate Replay was stopping and closing down. Then it shut down. I tried to reopen my project but got a message saying the file was corrupt or created in another version.

What is wrong with this program? lt gives me nothing but problems, and I can't afford to waste any more time on this project. This absolutely sucks. I'm so mad right now, I could throw my computer (which is high-powered and has 20 GB of RAM) through the window.

Ugh!
