Hi there,
Check your config in T559L.
Also check you PCR to ensure that it is generating your quota entitlements in your time type applied to your quota on correct day (ie 01/01/xxxx and not 01/04/xxxx).
I hope that this helps.
BTW - Please share your solution as there has been some really useful yet varied suggestions and i would be interested as to what was causing you the issue.
Will
