Padshop 2 - all samples missing

I just noticed that all samples for the patches in Padshop 2 are missing, means if I load a patch, I don’t get an error message and I can see that the parameters of each patch are loaded but the display of the sample(s) being used it just empty, hence there is no sound. I have the VST Sounds installed and the Library Manager does not show any issues, location contains the sound set files. I wonder where the samples are? In the default location there is just a “User Samples” folder with a demo sample, which I then can load and get a sound. But the patch related samples are missing.
Any ideas?
