Crash without errors, "No localized string found: Info.HaXeRunning"

I’ve been learning Haxe(Flixel) for a few months, but have run into a snag installing it on HaxeDevelop on a new computer. Any error while the export runs just crashes it, and with a neko export in 64 bit HaxeDevelop, the only output is:

No localized string found: Info.HaXeRunning

In HTML5 export it just freezes the window, and with 32 bit HaxeDevelop it just says “Done(1)” when it crashes. And when starting HaxeDevelop, it always shows:

No localized string found: Info.MTASCRunning
No localized string found: Info.MTASCDone
No localized string found: Info.MxmlcRunning
No localized string found: Info.MxmlcDone
No localized string found: Info.HaXeRunning
No localized string found: Info.HaXeDone
No localized string found: Info.PHPRunning
No localized string found: Info.PHPDone
Error: Display file was not found in class path

Error: Display file was not found in class path

A few hours on Google has found zero other people with the same problem, or any explanation of what that error means. (Hopefully this is the right place to ask because I’m not sure what to do at this point.)

The errors look like HaxeDevelop related errors.
Maybe try a different version or report issue at Issues · fdorg/flashdevelop · GitHub

If you want, you could try a nightly which seem to have some weird crash errors resolved. http://flashdevelop.org/downloads/builds/
