Hi Taolele and olenkabf,
Can you clarify if you are already using the latest version of Little Reader (currently it's version 2.0.616)? If you are not using this one yet, kindly try upgrading and see if the problem gets fixed.
It may also help if you re-download your content files (from your Account) as these have been updated just a few days ago. This applies if you already have an LR/LM license, though.
For both of you, kindly send us a Diagnostic Report so we can troubleshoot further. You may refer to this Support article for instructions on how to do this:
