Hello, I've just downloaded the Technic Launcher and downloaded the Pixelmon Modpack today.
When I tried to press play it shows the loading bar and loads for a few seconds and then closes the Technic Launcher. After a few seconds it reopens the launcher acts like nothing happened and minecraft doesn't appear at all.
I uploaded the launcher log file and also have a paste bin just in case https://pastebin.com/E2neKAGU
