The program is free and it is a gift. If you problem with it inform me. I promise no guarantee 100per cent of the answer, however, on every bugs report I will be glad. This allows to improve the program. First they visit the homepage of the program, perhaps the mistake is known ready and is repaired in new version. Formulate the mistake description in this way so I can reproduce the bug. (They Copy the mistake message) you can also send their(her) databases structure (as a SQL-Dump) if the data are not confidentially. A ER-diagram or specification of the data would be also meaningful. Support only by email.
