hi,
The information provided by you is very limited. Based on this information I would find it very difficult to provide an intelligent answer or even a direction to sort your issue out.
Can you provide details of your issue in PayPal.
For Example, what exactly do you mean by :
1) Autosweep
2) What are the few changes you made prior the reports not balancing?
3) What exactly do you know of italian double entry book-keeping which is the basis that PayPal uses for balancing accounts?
