Cannot get into my campaigns

I cant get into any of my campaigns after the update.

I get this:

Please advise.

It looks like the DCC ruleset is not installed, or not installed correctly.

Please try these steps:
* Start FG
* In the menu under your user name, select Data Folder option.
* Rename the rulesets folder to rulesets.old.
* Return to FG
* In the menu under your user name, select Update option.
* After update, try to load campaign again.

That fixed it, thanks!

Out of curiosity, any insight on why that would happen? I've updated to big updates before and never had this particular issue.

Thanks again. :)

Not sure. We did some renaming of some helper product IDs (used for rulesets/extensions) on the back end; and maybe the installer wasn't able to update them for some reason. That's my only guess right now.
