Damn Mssql

I got this 2 times :

SQL Server evaluation period has expired

I dont want to install mssql new every time so what to do now ?
Is there a version where this do not happen ...

[I dont want to pay for it ]

This is not a support forum for routers, mssql, computers, games, php, dedicated servers or anything else not directly related to Kal Online servers.

taken directly from the section rules also this forum doesnt support warez in any way so pay for it or leave it
infraction has been given since you cant follow a few simple rules.

also ever thought that there is a free edition of mssql2005?
