[Plugin: Login Dongle] Help – unable to login

Forgive my ignorance:

I downloaded and activated your plugin. I went to settings and added the question and answer. I then tried to login to my admin account and received this error:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, cgiadmin@yourhostingaccount.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

I did not copy any bookmarklet… How can I get back into my account to fix it?

thanks,

dan
