Hello,

 

I've been back and forth in emails with some CurseForge support staff on the issue but there's been no progress. In the CurseForge app, I have custom profiles and some public modpacks that will not load no matter what. I've goen through every link sent to me, I've reinstalled Minecraft, reinstalled the launcher, repaired the installations individually, uninstalled and reinstalled the public modpacks, downloaded the latest Java--all of it. But each time, I'm always met with either "java runtime exception", "exit code 1" on the rare occasions Minecraft does launch, or "java is out of date" (which literally cannot be possible since I reinstalled the latest version a few different times.) Making a new profile works, but I want to be able to play the ones I had before. 

I had gotten one of the old public Minecraft modpacks to work, the prehistoric one about dinosaurs being featured right now, but then it only worked once. I've tried to retrace my steps and it just would not work. I have genuinely no clue what's going on.

Please read the FAQ (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/) and post logs as described there, they may contain clues as to what is going wrong.
