急！C#连接Progress数据库

Question

各位大侠，有没有人用过C#连接Progress数据库，现在我是通过ODBC的方式连接的但是不成功

private static string conStr = "DSN=myProgress;HOST=erpsrv;DB=SS;UID=SYMIX;PWD=A1b2C3d4E5;PORT=30050";

提示以下错误：

ERROR [HY000] [MERANT][ODBC PROGRESS driver][PROGRESS]** -P and -U startup parameters require _User file records. (709)
