From the sales records I am allowed access to, your license serial number entitles you to use SQL Compare V8 and SQL Data Compare V8.
You can download these versions from our old versions web page using this LINK
Your support and upgrades option expired in May 2010, so if you wish to continue using the very latest versions of SQL Compare V10 and SQL Data Compare V10 once the trail period expires, you will need to purchase the software.
I recommend that you contact our Sales Team, firstname.lastname@example.org
, who will be able to provide all the options to you and provide the best advice regarding purchasing of our products.
