Upgraded 1.4.3 to 1.5.8, no bridgemanager in Util.php

I have the following issue when trying to bridge coppermine and phpbb3-3.0.7-PL1:
I upgraded my message board from phpbb2 to phpbb3 a couple years ago.  Recently upgraded to 3.0.7-PL1, everything went fine.  Time to upgrade Coppermine from 1.4.3 to 1.5.8, and it looks like the versioncheck is all correct, deleted the extra files that were unneeded.  Before upgrading, I disabled the bridge as last time I left the bridge on and was unable to log in.  Turned off the plugins and ran through the upgrade.  Now when clicking on "Admin Tools" in Coppermine, there's no choice for Bridging anymore.  When I manually go to http://railroadfan.com/gallery/bridgemgr.php, I get this: Coppermine critical error:
Unable to connect to Invision Board database !

When I try to log out of my local admin account, I get: A valid form token could not be found.

If I manually go to http://railroadfan.com/gallery/bridge/phpbb3.inc.php, i get this error: Not in Coppermine...
Please help me rebridge the site.  I also see a {JAVASCRIPT}  and {CREDITS} on every Coppermine page now as well, not sure if that's related or not.

Switch to the new curve theme.

Wanted to say thanks for the answers.. switching to the Curve theme actually just gave me the option for bridgemgr, but was still getting the issue of: I get this: Coppermine critical error: Unable to connect to Invision Board database ! MySQL said:
Logged into FTP, saw that three old files were still there in the bridge directory, I know one for sure was invisionboard20.inc.php, which must be why I was getting the Invision board errors.  Deleted these three older files, and then the bridge loaded and was able to bridge to phpbb3.
