Problems with the Technic Platform Launcher

[WDBForums]

Here's my dilemma in a nutshell:

I just downloaded the Technic Platform. But when I try to log in with my minecraft details, it gives me this error message: Auth Error: Invalid Credentials. Invalid Username or Password. Which is unbelievable since I did, in fact, input all my data correctly, from my Username to my password. I have my Username and Password written down in a journal, and copied it verbatim. And if you think I have my num lock on, well, hahah, it's not. So what do I do? What did I do?
