Hello,
Any assistance would be grateful!

I installed captcha, set to "math" and logged out of the site.
Now when I attempt to log in, I get an error message: "Invalid CAPTCHA token."

And now I am "locked out of the site!

Captcha 6.x

You can disable the module for example by manually editing your database (with PhpMyAdmin for example):
in the "system" table: set the status of the CAPTCHA module to 0.

Another more tricky way is renaming the directory with the CAPTCHA module just to get in, rename back to the original once you're in and disable it then the normal way

I would recommend using version 6.x-2.0-beta4, which is pretty stable now, instead of the 6.x-1.x branch, which is known to have problems with sessions, cookies and the CAPTCHA tokens.

If you want to stay with 6.x-1.0-rc2 however, you should check if you have an entry for uid=0 in your users database table and try your site out with another browser on a more harmless form than the login form (like a comment form)
