Update version does not work because use of trial software by Vdownloader
After making the recomeneded update (thorugh vdownloader) it appears a message that Vdownloader won't work because it was created with a trial software (Eaz"something".NET). I unistalled Vdownloader and am trying to instal a previoues version. I hope update versions are tested before sugestion!
Thanks
