Cannot switching DB provider from Jet to MySQL

[siyahrenk]

Hi;

I'm trying to switch DB provider from Jet to MySQL with using Plesk Reconfigurator. But it gives an error on everytime i try. What can i do ? Error is :

System.Execption: Unknown error 0xC00CE508 (COM Error C00CE508) at VDatabaseSwitch::SwitchDb at psaobselete.PSAMySQLDatabase.SwitchPleskDatabase(String new_provider, String new_host, String new_dbName, String new_login, String new_password, String new_port, String con_login, String con_password) at reconfigurator.Reconfigurator.Main(String[] args)

Plesk version is 8.6 for Windows (2003)
