Thanks!
I have checked the topic you told me about and another one mentioned there, but I am just a complete noob to understand what the possible solution is.
For example, they say:
You can try these options:
1. Replace the potentially problematic file filecache.py in the program folder ..\makehuman-community\makehuman\lib with the corrected one.
2. Install the nightly build, which, as far as I understand, should contain the fix.
I don't even know how to place that text info into a Python file, and replace it in the directory, for example.
I have downloaded Python, but when opening the file it just blinks and shuts down. When opening the filecache.py using Notepad, it wouldn't let me save it.
Looks like you need to have programming skills to resolve the problem.
I have reinstalled the app, but the problem is still there.
Very sad
