recent ms patch broke cp

Warning: DOMDocument::loadXML() [function.loadXML]: Char 0xDB85 out of allowed range in Entity, line: 1 in C:\Program Files\SWsoft\Plesk\admin\plib\class.DefPackageMng.php on line 243

Warning: DOMDocument::loadXML() [function.loadXML]: Char 0xD868 out of allowed range in Entity, line: 1 in C:\Program Files\SWsoft\Plesk\admin\plib\class.DefPackageMng.php on line 243

Fatal error: Call to a member function getElementsByTagName() on a non-object in C:\Program Files\SWsoft\Plesk\admin\plib\class.DefPackageMng.php on line 245

solution was to unistall kb936021

of course I am looking for a better solution than unistalling a needed patch. Please advise does upgrading to the latest fix this issue?
