new installation, old database = template issues

[Ratboy601]

So here's my story:

I was running 1.1.12.  I was hacked.  I deleted index.php, and reinstalled a fresh copy of it.  Didn't work.  So I set out to uninstall my mods (simple portal, donations, spam blockers) hoping it would allow me to reinstall and get a working version of index.php.  It did not uninstall properly.  I gave up on that, and deleted my whole installation.  I uploaded the large update package for 2.0rc4.  I created setting.php and settings_bak.php, then ran repair_settings, and set everything to the proper directories, and set it to use the same sql database I'd been using before.  Then I ran upgrade.php.  It worked perfectly, seemingly.  It took me to the main index after upgrade.  First link I clicked took me to the "can't find main_above" error.  I looked that up in the forums here, and in the index.template.php I changed template_html_above to template_main_above; and template_body_below to template_main_below.  This fixed the error, but rendered the default theme (Curve) unusable.  I was still able to navigate with the index links.  I opened my database files in phpmyadmin and changed the name of the default theme from Core to Curve, as it had retained the info from the old installation.  Now I have functioning forums and the theme is looking ok, but no main menu at the top of my screen.  Are there more things I need to change in my database?  Or is there another solution to this conflict between old database vs. new installation?
----------------- EDIT---------------
So I changed the main_above and main_below back to their original values, and now it works, apparently all because I changed the name in the database.  No problem anymore.

try running repair_settings.php and reset your themes paths.

I had already done that and double/triple checked it.  I was able to fix my issue above by replacing the original values of html_above and body_below.  Thanks anyway!

BTW, these forums have easily got the best support for their software that I have ever seen.  Kudos!  I am now thoroughly indoctrinated into the world of SMF...

Have a look in the database table "Settings".  Because you are using an old database I think the old themes and paths will still be in there. Edit or remove them.
