Fatal error: Class 'Piwik_Login_FormLogin' not found

After Update to 1.1.1 it worked fine but now if i want to login i get this error.


Fatal error: Class 'Piwik_Login_FormLogin' not found in *****/stats/plugins/Login/Controller.php on line 42

i delete all files on the server and uploaded again, but still the same.

Any idea what i could do to fix it?

On the next day i can login normally.

I have no idea what the problem was.
