'MEMB_INFO' table
- Unable to modify table.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert the value NULL into column 'memb__pwd', table 'MuOnline.dbo.Tmp_MEMB_INFO'; column does not allow nulls. INSERT fails.
[Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated.

creating and md5 will help my server from others getting the passwords? including me

Using MD5 your passwords will be in MD5 Hash Code and won't be easy to crack it or how its called.

it will be nearly impossible to decode it, unless you find the same exact MD5 hash somewhere in an website with MD5-decrypted codes database.

I need x64 support too..!! Using windows server 2008 x64 and MSSQL 2008

reup pls need it badly:)
