Connection Blocked!

Tried to use teamviewer to view my home desktop, as I normally do(not business, but personal use!) and it asked for the password displayed on the screen(I have the computer listed in my account/computers so I can remotely control it without having to have someone at the other end!) I closed, reopened and it worked fine. 

 

It crashed after a while, tried to reopen and its now telling me the connection is blocked because of multiple failed logins(I have only tried once my usual password, and nothing happened!) I can only try again in 42139 seconds!? What's going on!? 

 

Help!
