Up untill now, i've been using adobe flash cs5.5 for little animation tests, and a project i've been working on. However, My serial number became invalid, and I am no longer able to use it. I've had to downgrade to macromedia flash 8, which is a real pain in the butt because I've lost all of my AS3 files, which includes my OC sprite sheet, and my current project files. I'm trying to figure out how to fix this but it looks like I'm stuck using flash 8 until I figure things out. Still trying to work on a project though, so stay tuned for updates.
