Blocked access - too many repeated login requests

I tired to connect to another computer (I only ever log into one other computer).  Without realizing that the password had changed (I thought it may have been the connection) - I repeatedly tried accessing about 8-10 times.  Now, I am blocked access for 4217625 seconds.  I understand that there are security measures, but this is RIDICULOUS!  What can I do?  And do not tell me that I just have to wait....
