Several errors after Windows update

Hi

On the 15 of May there was a few updated that forced my Windows server 2008 to auto reboot, after that my piwik stats have not been working.

In the Visits over time window I get the following Error:
SQLSTATE[42000]: Syntax error or access violation: 1055 'piwik.log_action.name' isn't in GROUP BY

In the Visitors in real time window I get:
SQLSTATE[42000]: Syntax error or access violation: 1055 'sub.idsite' isn't in GROUP BY

I'm using 1.11.1

The Visits over time works for dates prior to May 15 but the real time tracking is still broken.

Things I have tested is:
* reinstalled 1.11.1 but left the data intact, same errors
* created an empty, ran the installation again with a new db name, and now the visits over time works but still same error on the real time window.
* Installed 1.12-b20 but it made no difference.


So the Visits over time error is probably due to corrupt data even tho I have used Repair on all the tables.
I have no clue on why the Real Time tracking doesn't work.

Any ideas?
