Hi Akuyali,
It's funny how there are always one or two things that we as authors just don't consider - that's one of them. Glad you have it working now anyway.
If you've switched from SQL Express to SQL Server, I'd suggest you have a look at the new Appendix B I wrote a few weeks ago -
http://p2p.wrox.com/topic.asp?TOPIC_ID=59199 - which covers all the steps you'll need to get your examples running with a 'full' edition of SQL Server. It's a little more tricky but not too bad. Connection Strings and permissions on the database are the two things you'll need to get working.
Let me know how you get on. The appendix is written using the full WroxUnited site as an example, but if you just substitute in the code for the chapter you want to work with, that'll be fine.
