How to activate a table?

Hi,

I created an Identity Audit Rule and I got this error when trying to enable it:

Error executing script 'ComplianceRuleWorkingCopy_ComplianceRule.ActivateWorkingCopy'.

Error occured enabling working copy

Error calling method 'ActivateWorkingCopy'.

Could not create collection object for table ComplianceRuleHasMControl.

Could not create single object for table ComplianceRuleHasMControl.

Table ComplianceRuleHasMControl is deactivated. You cannot create an object for this table.

So the question is, how can I activate that table?

Thanks,

JM
