Fatal error on database 'restore_backup' install:

Fatal error: Cannot instantiate non-existent class: cpm in /homepages/31/d100677039/htdocs/performance/forum/Sources/Load.php(1733) : eval()'d code(231) : eval()'d code on line 3

Greetings all... I've been seraching through the threads trying to determine what needs to be fixed on my 'fresh' install, but so far no luck, if this issue has been discused before can someone please point me, or tell me what to do to repair the error.
Link to the install... http://www.performanceefx.com/forum/index.php
Here's the steps that I took:
1/ Make a fresh and empty MySQL db;
2/ Install SMF 1.1.1 full;
3/ TP .097 manual install + Premade_manual_install_files;

At that point everything was operating correctly and looking good, but then I used the SMF 'restore_backup' to reinstall my most current save of the forum database and that's when the above error came up.
This backup was taken while SMF 1.1 RC3 was being used for the forum, is that what is causing it to throw the error? If so, can this install be fixed and saved, or must I start over?

Thanks... Ken

One thing that I've found on the theme settings is that the page you see currently is for the forum's default theme Helios_Multi... if it is changed to the SMF Core theme it looks much more normal, but the error message is still there of course.Sorry, this Core theme error came from the cpg gallery not being installed yet.

Note that no themes have been installed, the only thing on this install is SMF 1.1.1 & TP 097, plus whatever the db backup had in it, so do I need to go through and remove all instances of code for the the Helios theme that must have been in the backup?

EDIT: It appears that this is a theme problem, caused by the db backup having theme code in it while there are no themes installed to this fresh install of SMF & TP, I'll try to clean up the files myself, but may need some help later.

You could try reinstalling Helios.  Then uninstalling it.

That seems to have worked very well!
Thanks Thurnok.
