I was downloading it, it was going smoothly then it said Launching... then it said this in the codings: "[09:57:47 INFO]: Minecraft Launcher 1.5.3 (through bootstrap 4) started on windows..."

After getting a new laptop (I previously played Minecraft on a Macintosh and I worked fine) I installed the Minecraft Launcher and this problem above happened. I also saw this on the output thingy: " Error: Could not find or load main class net.minecraft.client.main.Main
Java HotSpot(TM) Client VM warning: Using incremental CMS is deprecated and will likely be removed in a future release" If someone could tell me what this means it would mean a lot to me.
I love you guys' games (especially Minecraft!) And am exited to see how Scrolls turns out. It would be very appreciated if you could help me in these matters and I hope you have a Wonderful Day and a Very Merry Christmas.
