So windows updated and now Flash CC no longer works (0xc00007b). I don't have any older versions, and if I did I wouldn't be able to open my sprite sheets in them most likely, because they're all AS3.0 instead of AS2.0
I have a lot more updates to install, and plan on doing so gradually throughout the coming weeks/months. Firefox was also broken in a similar way, so it's probably a software issue that will be fixed by updating windows to be compatible with these newer versions.
wish me luck.
