Crash on startup, Curse Launcher Custom pack.

  • Tech Support section is for getting help with FTB related problems. If there's a repeatable issue that can be labeled as a bug, then please use the issue tracker for the pack or the app at GitHub issue trackers - If there's no repository for a pack that means that the pack is old and/or will not be updated. Bugs for older packs will not be fixed, unless they are critical.

Title:
Crash on startup, Curse Launcher Custom pack.
Launcher Version:
Latest Curse Voice, plus MultiMC
Modpack:
My own custom
Modpack Version:
N/A
Log Link:
Details of the issue:
I have my own custom modpack I am testing Curse Voice with, I did the foolhardy thing and just updated all the things now I get this odd crash mentioning something about not being able to assigns something or other.
The log is too vague to determine a culprit. Thaught it was a Forge thing but attempts to update it have turned up nothing.

Things I have tried;
Unsuccessfully updating forge, (there's no clear way to do it with Curse Launcher.)
Updating to Java jre1.8.0_51. (thought it could have been a java thing.)
Copypasta the mod instance file from Curse to MultiMC to use it's forge updateing function.
Fetal position and weeping.

Thing I haven't tried; Disabling the mods I updated one by one. (I sort of half did it, I'd rather not have to do it, plus I didn't pay attention to which ones I updated...)

What I'd really like is insight as to what that error in the log means.
Also Curse Voice did appear to just update.

Update: Was apparently a forge thing, I deleted all the files in the 1.7.10 folder it generates, the files then regenerated.
Still have no idea what caused it though. If anyone has insight as to what happend it will still be welcome.
I hate fixing things without knowing how I fixed it.

Your launcher uses java6. Fix that.
