Error when I upgrade my piwik to verion 2

Hi folks,

I hope you can help about my problem. I have a problem in upgrading my piwik to version 2.
When i tried to update to V. 2. I got this error. (screenshot below) and also I can login anymore.

Any answers will be appreciated.


What error message is it please (easier than video for other users to see the solution if they have same error message)

this is the error I got when I tried to login.

Disk quote exceeded error, means the disk seems to be full on the server ?
