I can't start SQL server

I have the SQL server that came with Web Developer Express or C# Express, I don't remember exactly which one...

The thing is, the service won't start.

Has anyone experienced this problem here's the error log:(the files it tries to open are not read-only):

Thanks.

Yep, having the same problem. Something about SQL Server not allowing remote connections, even if it's actually local (something to do with logical connections). I configured mine per the stuff I've read, but still get the same errors.

Let me know if you've found anything if you happen to check back here.

Thanks in advance.
