[Urgent] Attention to anyone using LOFT Source

The MySQL .NET Connector has a bug, its not happen always, but it happen like 3 or 4 times a day, i search the MySQL Knowledge base and some report that bug too.

look at the errors:

Code:
MySql.Data.MySqlClient.MySqlException: Duplicate entry '' for key 1
   at MySql.Data.MySqlClient.MySqlStream.OpenPacket()
   at MySql.Data.MySqlClient.NativeDriver.ReadResult(UInt64& affectedRows, Int64& lastInsertId)
   at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet()
   at MySql.Data.MySqlClient.MySqlDataReader.NextResult()
   at MySql.Data.MySqlClient.MySqlCommand.ExecuteReader(CommandBehavior behavior)
   at MySql.Data.MySqlClient.MySqlCommand.ExecuteDbDataReader(CommandBehavior behavior)
   at System.Data.Common.DbCommand.System.Data.IDbCommand.ExecuteReader(CommandBehavior behavior)
   at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
   at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
   at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable)
Code:
System.ArgumentException: Column 'UID' does not belong to table Character.
   at System.Data.DataRow.GetDataColumn(String columnName)
   at System.Data.DataRow.get_Item(String columnName)

i suggest if you are planning to release your server to public, move to another database server like SQL Server.

cuz when that problem happen, some character information replace with 0 in the database

The problem is not in LOTF Database code, you are true the code had one problem, but i fix it, i trace the code, but the problem is in the MySQL .NET Connector, and there are alot of people post it in the mySql forums, the thing is the problem happen randomly
