Tekkit Isn't Launching!

[Mister Technic]

Hi there! Let me get straight to the point. Whenever I launch Tekkit Classic, it launches. It starts off with a white screen, then a black screen, then the Mojang screen. After about 5 seconds, the window closes. Please help, Tekkit is so fun, and I would hate not being able to play it anymore.

Try adding more RAM to the launcher.

Open the launcher, click on the cog gear up at the top right corner next to the X button.

Where it says "memory" and has a scroll down menu, click on the menu and select a good number. Depending on how much RAM you have, thats how much you can dedicate. I have 8GB of RAM installed, and I have 6GB dedicated to Tekkit.
