Ooops...just had my first macuco issue...

I clicked 'sign off' at the bottom left
I then signed on with another gmail account for the first time using this app.
Now I am stuck getting this error:
"Request URL Too Large
The requested URL /accounts/ServiceLogin...is too large to process"

I unfortunately left 'remember me' checked...so even if I close down Macuco it automatically takes me to this error and I can't break out of it.

(Not sure if it matters, but the email account name is indeed a long one: 15 characters).

Heeelp
