Hi Svetlana, can you please check that you've installed the latest version of the Little Reader software (version 3.4.1565)?
To check which version you have, open LR and go to TOOLS > Software Information and look for "Software Version." if the number you see in your LR is smaller than the one mentioned above, that means you are using an old version.
Please download the new installer file from your
Account > Purchases > Little Reader page, and run the installer to update your software.
After updating Little Reader, try downloading the starter content again.
I hope this helps! If you are still having problems, do let me know which specific starter content you're trying to download so we can check the file accordingly.
