Install Screen After Upgrade to v2.5

After upgrading my site to v2.5 I am getting the "nopCommerce installation" screen when I now visit my site. I have followed the correct steps for upgrading, I think!

1. I am upgrading from v2.2 to 2.5 so I went one step at a time, i.e. I ran script "nopCommerce_2.30_UpgradeScripts" on my database, then the 2.4 one and finally the 2.5 one.
2. I downloaded all my current files from my site.
3. Unzipped v2.5 "no source" that I downloaded from nopCom site.
4. Uploaded to my web server and replaced App_Data\Settings.txt and App_Data\InstalledPlugins.txt files

No when I visit my site I get the installation screen.

Can anyone advise?

Thanks in advance...

Forget this, my fault :(

For some reason after I uploaded my settings.txt file it was empty. I re-uploaded again and checked it contained the required info. After this I could get to my site.
