Dammit! I need help!

So, i was removing some elements on my computer and cleaning things up…i removed fireworks MX, to make some space…i have Fireworks 8 and wanted to keep it…now, windows doesn’t recognize 8 as the program to open png files with…it only gives me the option for paint and photoshop to open these files…

anyone have an idea of how this happened, or what i can do to fix it?

Thanks!
