You need to log in with your Minecraft account details. If you have a Mojang account, use your email instead of your username. You need to have bought Minecraft to use the Technic Launcher.

I've already mentioned the causes and fixes - the checking is done by the Minecraft servers. If it works with the Minecraft launcher, use the same details. You don't need any sort of Technic account to use the Launcher, it doesn't run off them.
