Today FlashDevelop got stuck on startup into an infinite loop of the following error:
Binary stream '0' does not contain a valid BinaryHeader. Possible causes are invalid stream or object version change between serialization and deserialization.
I found this really old forum post that said to delete the whole FlashDevelop app data folder.
So, I deleted/renamed the folder located at C:/Users/YOURUSERNAME/AppData/Local/FlashDevelop, and it works again!
I use FlashDevelop for a lot of work projects. It’s a much better IDE for writing code-based ActionScript 3 projects than Flash itself.
Today, out of the blue, it started freezing on startup while trying to load the last project I had open. I thought I’d post about it in case a.) it ever happens to me again, or b.) it helps you, dear reader.
A quick Google search produced this forum thread, which solved it for me.
The solution was to rename/delete the file C:\Users\[USERNAME]\AppData\Local\FlashDevelop\Data\ProjectManager\Settings.fdb, which probably got corrupted.
Back to work! 🙂
