preg_match error after installing plug-in

Having an issue after I installed the plug-in.

After installing, I’m getting errors above my header like this:

Warning: preg_match() [function.preg-match]: Compilation failed: missing ) at offset 77 in /home/angusbra/public_html/wp-includes/class-wp.php on line 204

Warning: preg_match() [function.preg-match]: Compilation failed: missing ) at offset 77 in /home/angusbra/public_html/wp-includes/class-wp.php on line 205

Warning: preg_match() [function.preg-match]: Compilation failed: missing ) at offset 72 in /home/angusbra/public_html/wp-includes/class-wp.php on line 204

Any help would be greatly appreciated!

Thanks,

Daman
