PSPx5: Cannot find downloaded content after install

[Stoltenbergen]

So here's the problem: I head over to the icon in the top-right corner, "Corel guide". Then I go to the tab "Do more".
From here I can download frames, patterns, preset shapes etc.
However, I cannot find the downloaded content after installing. I have restarted PSP afterwards, but to no avail. I would try to uninstall and reinstall the packages, but I can't find a way how to do it.

I am using Windows 8 64bit, and the latest update for PSPx5.

So after troubleshooting a while, I decided to take a bite of the rotten apple and I uninstalled the entire program.
I reinstalled and the downloaded content installed correctly afterwards.

It seems reinstalling PSP is the solution for many problems with this program.. Maybe devs should look into this.
