The program is free and it is a present. If you problem with it inform me. I promise no guarantee 100per cent of the answer, however, on every bugsreport I will be glad. This allows to improve the program. On the spot of the commercial software firms I would pay even for every bug-message money. This is not possible here. You have the program free you can also do for other something. First they visit the homepage of the program, perhaps the mistake is known ready and is repaired in new version. Formulate the mistake description precisely. (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.
