Problem when upgrade to 1.0.0 version

After I upgraded to version 1.0.0 (from 0.6.3 version) of this plugin, I found the following error message:

Table ‘MYDB.DBPREFIX_wsal_occurrences’ does not exist

And the following is an example of an error tracking from newrelic for the above error:

After that, I could not open the “Audit Log Viewer” page (error 503 from varnish, because the request timed out).

So, for a while I deactivate this great plugin, until the next new version.
