Hi. I upgraded from V2.1.1 to V2.1.2 for the website http://www.proaudiohome.com
I get the following error after I upgraded the files as below.

Notice: Use of undefined constant TB_THEME_ROOT – assumed ‘TB_THEME_ROOT’ in /home/proaudio/public_html/tb_themes/shoppica2/library/Context.php on line 3Warning: require_once(TB_THEME_ROOT/library/DataBag.php) [function.require-once]: failed to open stream: No such file or directory in /home/proaudio/public_html/tb_themes/shoppica2/library/Context.php on line 3
Fatal error: require_once() [function.require]: Failed opening required ‘TB_THEME_ROOT/library/DataBag.php’ (include_path=’.:/usr/lib/php’) in /home/proaudio/public_html/tb_themes/shoppica2/library/Context.php on line 3

PLEASE HELP
