Issue: I have been able to play fine the latest Direwolf 20, but suddenly when launching the modpack from the FTB Launcher, the launcher is just a grey screen and never does anything. Vanilla launcher works fine. I have updated drivers, uninstalled and reinstalled everything (MineCraft, FTB, different ModPacks). I have seen that several people have had this issue, but I have not seen a fix. Can someone help or link me to the fix thread?

Bottom line up front: My java updated to a version not compatible with my OS, i fixed that and the issue resolved. Essentially, when my Java updated, for some reason it downloaded the 32 bit instead of 64 bit. I got rid of the 32 bit and downloaded the 64 bit. No issues since.
