Slitherine

I recently moved to a new laptop and wanted to install Pz Corp to the device. I had kept all the install packages (I have Pz Corp, Allied Corp, Africa Corp, Soviet Corp and all Grand Campaigns and so I thought I would just install Soviet Corp first (since it looked like it contained all the base Pz Corp components. After installation I could only see Soviet Corp, so I then began installing the remaining pieces in the following order:

Soviet Corp
Allied Corp
Africa Corp
All Grand Campaigns
Pz Corp

After completing all this I can see/play everything except the basic Pz Corp. When I go to launch the basic game it tells me I have not purchased the game yet and launches a dialog box asking me if I would like to download and purchase now. If I say yes, it takes me to the Slitherine Website.

Is there a way to correct this issue or did I box myself in by installing in the wrong order (I couldn't find the original Pz Corp exe and had to request a new download, hence the reason it was last) and now I have to uninstall and reinstall in a specific order?

So I have found my own answer, but in case someone else has the issue, here is my solution.

It appears the newly downloaded PZ Corp install package did not contain the latest version. So I downloaded and install Update 1.24 followed by update 1.25, and suddenly I could now access Pz Corp again as well as all the other content.
