There's a forum post on the MC Forums called "Can't connect to minecraft.net" with a separate launcher download that fixes that problem. Now we just wait for a fix, I guess.
In .techniclauncher I have: cache, launcher, logs, technicssp, tekkit, temp (all of those are folders), launcher.properties (Properties file), and technic-launcher (the exec. jar)
On the Minecraft forums. A moderator there provided a download link for a few other people who had the same problem.
EDIT: I can post a link to that thread, if you need to see what I mean.
Launcher Version: 1.0.1.1
Operating System: Windows 7 Home Premium, 64-Bit OS
Java Version: JRE 7 for Windows x64
Antivirus Program: Norton Internet Security (Was preinstalled on this new laptop)
Description of Problem:
When I enter my Mojang account credentials into the Technic Launcher, a box with the error message "Unable to authenticate account with minecraft.net" appears. On a similar note, my default Minecraft Launcher could not connect to Minecraft.net, but a moderator provided a download link to a separate launcher that could allow me to login to Minecraft.
