Can't Access Account?

I just installed Piwik and everything went smoothly. until I tried to access Piwik for the first time. I got into the program when I first installed it and it asked me to setup a super admin user but when I closed the program and tried to enter via the login screen it will not accept the username and/or password.

Obviously I have access to all the files on my server does anyone know where the login file resides on the server? If so what is the path?

After repeated tries I get the following message:
Error: Form security failed. Please reload the form and check that your cookies are enabled. If you use a proxy server, you must configure Piwik to accept the proxy header that forwards the Host header. Also, check that your Referer header is sent correctly


Okay. I switched browsers. I switched from Chrome to Firefox and I was able to access the account.
Does this have something to do with cookies?

Maybe you use extension on chrome to supress referrer header ? or try reloading the page and try again ?
