Fixing AnyConnect Problems

I was connected to my AnyConnect SSL VPN a few days ago when our data center had an outage. When my connection was available again, my VPN would no longer log in. AnyConnect simply complains that:

The VPN client driver has encountered an error when connecting through Cisco AnyConnect Client.

 So far, no troubleshooting steps that I've found anywhere online have helped except this one:

And I quote:

This issue can be resolved when you uninstall the AnyConnect Client, then remove the anti-virus software. After this, re-install the AnyConnect Client. If this resolution does not work, then reformat the PC in order to fix this issue.

I don't have antivirus software installed. Yes, I ended up *reformatting my PC*. And this is the third time in as many years that I've had to do it.
