So,I haven't played Modded Minecraft on Curse for a while,so I decided to try it again.When I installed Twitch for Curse,I went and installed a modpack.I tried running it,I logged in my Minecraft account and clicked play but all it said was ''An unexpected issue has occurred and the game has crashed.We're sorry for the inconvenience.''Then,I found an answer to that problem so I went to Settings>Minecraft and turned on Jar Launcher.I tried to run the Modpack again,but it took me to the old launcher.I tried to play on the old launcher,but all it said was ''Error occurred during initialization of VM
Could not reserve enough space for 3145728KB object heap
Java HotSpot(TM) Client VM warning: ignoring option PermSize=192m; support was removed in 8.0''.I have the Java 8.Also,when I said that I haven't played on Curse for a while,when I did play on it,it worked perfectly fine and nothing since that hasn't been changed on my PC.Please help!
