MCL-455Dev Launcher cannot launch renamed (possilby modded) .jar files.
After the update to 0.9.2 the Dev Launcher is giving an error and fails to launch any renamed .jars. I have a 1.5.1 jar modded to play The Aether mod, renamed and placed in another folder (along with modified/renamed .json) and any time I try to launch it I get this bit of code.

Everything worked just fine yesterday, I haven't done anything to the files, and trying to make a new modded .jar wont work either.

Confirmed, but not a problem of the launcher.
minecraftArguments is missing.
Update your .json files.
Thank you, that was it.
I don't recall needing to do this before, is this just due to a change in the .json file, or does this happen with every Launcher update?
Was a single change, but see the red text in the launcher. Everything can change...
Alright, fair enough. Thanks again!
I am having a similar problem - can you expand on how I "update" my .json file?
I added the name when I modded the version and the "name" is still showing, what do I need to do?
Edit - worked out that it is the .json file within the modded folder and not the .json version file
All Good
