My b2evolution Version: 2.x

I'm new to b2evolution and have version 2.4.2 installed. I was trying to create a new skin by modifying the images, background, etc. from the evocamp skin and succeeded in doing so.

However, I did a dummy move and deleted the posts and blogs I did not need. I happened to read this after the fact: http://manual.b2evolution.net/Sample/example_blogs

Now I see a default page saying I haven't set a default blog. I tried going into the admin section>Blog Settings>URLs and changing the Blog Base URL to Default blog in index.php but that did not work because after saving it the URL would go back to http://www.website.com/example/index.php?blog=2
I even tried to enter an absolute URL but that doesn't work either. In Global Settings>General>Display Options, is says No Blog and in the drop down does not have the other blog I want to display.

I'm assuming I have one of two options. One and probably easier than the second option that I'm doing now would be to reinstall everything and not delete anything or two go into the SQL database and search for a way to make the blog value 0 instead of 2. Does anyone know where to look in SQL to solve that or another option besides reinstalling? Thanks!
