An error occurred when loading the task sequence

Recently I ran into a problem where I was unable to open and edit any of my task sequences. It didn’t matter whether I was accessing ConfigMgr from a remote console or locally on one of my site servers – they would fail to open. The error that I was getting:

"An error occurred when loading the task sequence"
I tried rebooting the problem site server but still no luck. According to KB2468097 this is caused because the BDD_* WMI classes are no longer correctly registered under the \root\SMS\site_ namespace in WMI.

• Close all of your remote and local SCCM admin console sessions
• Log on to your Configuration Manager server and select Start -> All Programs -> Microsoft Deployment Toolkit -> Configure ConfigMgr Integration
• In the Configure ConfigMgr Integration wizard, select “Remove the ConfigMgr custom action definitions” and then click next to remove all the definitions
• Re-run Configure ConfigMgr Integration again, and select “Install the ConfigMgr extensions”

I also found that my site server needed to be rebooted after following the steps outlined above before the issue was resolved. This problem occurred on consecutive days a few weeks back but has yet to resurface since.
