Fatal Error afterUpload to VQMOD

Hi there,
I am very new to all this and, in hindsight, should have sought more info.
In short, I crashed my site, after uploading to VQMOD. I now get FATAL ERROR messages be it when I try to log in to OpenCart Admin or view the site on the web.

Error reads:
Fatal error: Call to a member function getElementsByTagName() on a non-object in /home/salonmeg/public_html/vqmod/vqmod.php on line 242

Any suggestions on what I can do to resolve this?

Appreciate your help.
Paul.

After uploading do you install that module on your site??
