patch database

can someone help me figure out how to fix my database patch? i upgraded from 1.2.7 to 1.3.0.1 and the database changed and then changed back to the old version. What do i do?

Thanks to who can help me!

Could you give a step by step of which Zen Cart file you downloaded for the upgrade and the exact steps you took to do the upgrade?

It does not make sense that it upgraded then changed back ...

i downloaded zen-cart-v1.3.0.1 from my server and when i did i got this message

Your database appears to need patching to a higher level. See Admin->Tools->Server Information to review patch levels.

and when i went to check the patch level this is what i saw

im not sure what to do.

If you go to the /zc_install what does it say it needs to Upgrade on the databases?

im not sure if this is what you were asking for or not? but heres what i got

Database Setup
On the next screen, you are asked for Database Information about your MySQL database, username and password. These can be obtained from your cPanel or equivalent control screen provided by your host. If you do not have a clean MySQL database setup with a username and password, you will need to create one.
Contact your Hosting site if you need assistance in creating a MySQL database table and/or username and password. Note that you need to have your database and userID created before the Zen Cart™ installer can continue past this screen.

Other information on this screen:
At this time, MySQL is the primary operational database type.
Future releases may support other database types.

We recommend that you store your Database Sessions in your database for security purposes.

On the 3rd screen ... the Zen Cart™ Setup - System Inspection

There is a long check list then buttons at the bottom

One of the buttons reads: Database Upgrade

If you click that button, you will see several checkboxes ...

What, if any are checked?
