Could not find the main class: cz.vity.freerapid.core.MainApp. Program will exit.

I Have just downloaded vity's free rapid downloader & did donate to the cause.
I had been using it several months w no trouble & all of a sudden it went screwy on me.
After downloading again,I keep getting this error message & program will not open.

Could not find the main class: cz.vity.freerapid.core.MainApp. Program will exit.

Would someone please advise what the problem is.
Thank you to anyone who will answer.

Such exception usually means that you didn't extract ZIP file properly with complete structure.
Check Preserve folder structure while extracting.
