Error When printing aeroo reports

[Ammoun84]

Dear all,

I installed aeroo report module in OpenERP 6.1. I'm working with the OS Windows 7.
I tried to test the existing report sale_quot_aeroo_report but i get this error:

Error while generating the report.\nChar 0x0 out of allowed range, line 1, column 2\nChar 0x0 out of allowed range, line 1, column 2\nFor more reference inspect error logs.\n\n(<type 'exceptions.Exception'>, Exception('Aeroo Reports: Error while generating the report.', XMLSyntaxError(u'Char 0x0 out of allowed range, line 1, column 2',), 'Char 0x0 out of allowed range, line 1, column 2', 'For more reference inspect error logs.'), <traceback object at 0x049CA350>): ''>\n", "fault_code": "warning -- Aeroo Reports: Error while generating the report.\nChar 0x0 out of allowed range, line 1, column 2\nChar 0x0 out of allowed range, line 1, column 2\nFor more reference inspect error logs.\n\n(<type 'exceptions.Exception'>, Exception('Aeroo Reports: Error while generating the report.', XMLSyntaxError(u'Char 0x0 out of allowed range, line 1, column 2',), 'Char 0x0 out of allowed range, line 1, column 2', 'For more reference inspect error logs.'), <traceback object at 0x049CA350>)", "type": "server_exception"}}
I tried with other reports like purchase_quote_aeroo_report but the same error persists.
If Someone can guide me to find the problem i'll be very thankfull.
