Suddenly can't access my user account?

[Virusfist]

I have the Windows 8 Developer Preview OS on my computer. Last time I restarted my computer I couldn't log back in to my primary user account. The email was correct and I typed the same password as I always use but it kept saying the email or password was incorrect. And to be clear I absolutely know I'm using the right password. It seems like the password changed itself somehow. Basically now I can't access that account and am having to use a secondary user account that doesn't have much on it. Can anyone help me gain access to my main user account? Or change the password somehow? I've tried about everything I can find on Google and nothing seems to work. Thank you

may try it but if the second user he is using now is not admin.... where are you from, I ask because some have different keyboard language setting and if your keyboard is not set in the same language as the one you create your password, well it can make a difference.

Ya I've been unable to change the password from the account I'm on. The only options I can find are "Set up parental controls, change the account type, delete the account, & manage another account." I use my laptop keyboard and an external usb keyboard but I'm in the United States and haven't ever used a different language.
